Length of one mile in kilometers. Land mile

More than two hundred years ago, France passed the Law on the Metric System of Measures, which has been used by most of the world since then. It's about meter and gram. Before that, each country had its own methods of measuring distance and mass, for example, the arshin and fathoms among the Slavs. Now it seems to us that such measures are terribly inconvenient, everyone is accustomed to the fact that in any country the same measures of measurement. But countries such as Myanmar, Liberia and the United States do not use the generally accepted metric system.

Measurement, for example, distance, is still carried out using miles, and the question of how many kilometers are in a mile or how many centimeters are in an inch is often of interest to the domestic consumer of foreign, namely American, products.

The history of the existence of the concept "mile"

This is a measure used in a number of countries of antiquity, and its name comes from the Latin mille passuum - this was the name for the distance of a thousand double steps taken by Roman soldiers on the march, fully dressed in the armor of that time. But there is no single system for converting miles to kilometers. This is due to the fact that in the 18th century there were about ... fifty different miles in Europe. The smallest mile, in comparison with a kilometer, is the Egyptian one, equal to 580 meters. And the Old Norwegian mile, equal to 11.3 kilometers, has the maximum value.

Mile in different countries

The French had at least two miles - land and sea, and their dimensions were deduced as part of the length of the earth's meridian arc. How many kilometers in an overland mile were calculated from 1/25 ° of the earth's meridian, and this is 4444.4 meters, that is, almost 4.5 kilometers, similar to a nautical mile, 1/20 ° of the earth's meridian, and this is 5.555 km.

Milliatry, also known as the ancient Roman mile, equals 1.482 km. The Old Russian mile was equal to seven versts, and now it is almost 7.5 kilometers, approximately the same value - 7420 meters is the German one mile. How many kilometers do Swedes and Norwegians equate to one mile, so this is 10.668 km and 11.298 km, respectively. True, after the adoption of the law on metric measures, both countries equated a mile to ten kilometers exactly.

Why the US does not accept the metric system

Why is the country with the highest degree development still uses the old calculus? This question is related to many nuances. They tried to carry out the transition many times, but various historical events and financial expenses required for such a business interfered. For example, having gained independence in 1776, the United States wanted to put things in order in the measurement system. But it turned out that this would require sending a delegation to France. At that time, such a trip would have been very expensive, and the case was postponed indefinitely. When ended Civil War in the USA (1865), most European countries have already switched to the metric system, and this fact could no longer be ignored. In 1866, an act was signed declaring the metric system official for lawsuits, contracts and transactions. That is, for almost 150 years, the United States should have used the metric system accepted by the whole world. In fact, the situation is this: in the United States, the use of the metric system is "recommended". It is not mandatory, because only 30% of the products are "metrified". This applies to pharmaceuticals, where only the metric system is used, and otherwise they can indicate data on two systems.

How many kilometers per mile are there now

Nowadays there is a concept of two miles - sea and land. The nautical mile was equated to 1862 meters, the American land mile is 1.609344 kilometers. To calculate how many kilometers are in a mile, for an approximate value, simply multiply the number in miles by 1.6. So, a car speed of 40 miles per hour would be approximately equal to metric 65 kilometers per hour.

Mile Is a unit of measure for distance introduced in Ancient Rome... Translated from latin means 1,000 steps. The military - the Romans, walking along the roads of the empire, measured distances in double steps. The original Roman mile corresponded to 1,475 meters. This measure was used in many countries in antiquity. However, with the introduction of the metric system of measures known as SI, its use has declined significantly. One way or another, today in some countries this track length measure is still used. It should be noted that the size of a mile varies greatly in different parts of the world from 0.58 km to 11.3 km. Moreover, back in the 18th century in Europe, there were about 46 units of measurement, which were called miles.

Today, in everyday life in different areas there are several types of miles. Speaking about the most popular of them, you can name:

Land miles
Nautical miles

Let's consider each of them in more detail.

Nautical miles

A nautical mile is a unit of measure for the distance, between destinations, traveled by a ship. This measure is widely used in navigation, as well as in aviation. In fact, this is the average arc length of one arc minute of the meridian. Gerardus Mercator, a Flemish cartographer and geographer, suggested using this measure. In Russia, the nautical mile has been used since the time of Peter the Great. And today, when mariners are offered to go for kilometers, they answer that they do not plan to do this. However, this is justified. After all, a nautical mile is, in fact, a path corresponding to the distance between two geographical coordinates in one minute of latitude.

So how many kilometers are there in a mile? Here are the formulas for converting miles to kilometers and back.

Formula for converting nautical miles to kilometers

1 nautical mile \u003d 1,852 meters \u003d 1.852 kilometers

We derive the formula for converting a kilometer to a nautical mile

1 nautical mile \u003d 1.852 kilometers
1,000 nautical miles \u003d 1,852 kilometers
1 kilometer \u003d 1000/1852 miles (roughly equal) 0.54 miles

Formula for converting kilometer to nautical mile

1 kilometer \u003d 1000/1852 miles? 0.54 miles

Land miles

The land mile is used mainly in English-speaking countries, and corresponds to a value equal to 1 609 meters. The land mile is used in the United States and is sometimes referred to as the American mile for this reason. Accordingly, if you want to know: how many kilometers are in an American mile or, which is the same, how many kilometers are in the United States, then the above value should be used. Also, this unit can be found under the names British or statute mile.

In addition to those described, there are also:

a geographic or German mile equal to 7,420 meters (7.42 km);
old Russian mile equal to 7,467.6 meters (7.4676 km).

How many kilometers is 1 mile in Russia?

I would also like to note that in Russia this measure of length is not used, because there is nothing to measure in these units of measurement in the Russian Federation. Seafarers have global nautical miles (see above).

Often there is a need, for example, when solving a problem, to find out: how many miles are in a kilometer or vice versa? Here it is worth clarifying which mile (land or sea) needs to be translated. Or maybe an old Russian mile or a German one? And already, depending on this, this value can be converted into the usual kilometers. Let's consider several tasks for converting miles to kilometers and back. To be specific, let us clarify that to solve problems we will convert nautical miles to kilometers (1 nautical mile \u003d 1.852 kilometers).

Miles to kilometers convert online

We suggest using our calculator for converting miles to kilometers online.

Very often in English and American literature one can find not entirely clear metric units such as miles, feet, yards, inches - especially if the translator was too lazy to convert them into meters and kilograms that are convenient for our perception.

A mile (from Latin milia passuum - a thousand double Roman steps) is a path measure for measuring distance.

1 mile \u003d 1.609344 kilometers

The mile was used in a number of countries in antiquity, as well as in many modern countries before the introduction of the metric system of measures. In countries with a non-metric system, the mile is still used. The mile is different in different countries and ranges from 0.58 km (Egypt) to 11.2 km (Old Bohemian mile).

Ancient Roman (milliatrium): 1 mile \u003d 1.598 km (according to other sources, 1.480 km)
Old Russian: 1 mile \u003d 7 versts \u003d 7.4676 km
British and American: 1 mile \u003d 8 furlongs \u003d 1.6093 km
Geographic (German): 1 mile \u003d 1/15 ° equator \u003d 7.420 km

Nautical mile - a unit of measure for distance used in navigation and aviation.

Originally nautical mile was defined as the length of an arc large circle on the surface of the globe, one minute of arc. Thus, moving one nautical mile along the meridian roughly corresponds to a change in geographic coordinates by one minute of latitude.

By modern definition, an international nautical mile is 1852 meters (exactly).

International Nautical Mile \u003d 10 Cable

UK nautical mile \u003d 1,853,184 meters (up to 1970).

How many kilometers per mile are there now

Now the concept of two miles takes place - nautical and land.

The nautical mile was equated to 1862 meters, the American land mile is 1.609344 kilometers.

To calculate how many kilometers are in a mile, for an approximate value, simply multiply the number in miles by 1.6, that is, approximately 1609 meters are obtained. A nautical mile is also larger than a land mile and comprises approximately 1.852 kilometers or 1852 meters.

So, a car speed of 40 miles per hour would be approximately equal to 65 metric kilometers per hour.

1 mile equals:

1.609344 km;
1609.344 m;
16,093.44 dm;
1609344000 μm;
63360 inch;
1609344 mm;
160,934.4 cm;
5280 ft;
1760 yards;

Mile

This measure of length came to us from antiquity and has many varieties and, as a result, values \u200b\u200b- from 580 meters in the Egyptian mile to more than 11 kilometers in the Norwegian. However, in the vast majority of cases, a mile is understood as a British (or American) mile - 1609 meters 34 centimeters. So if in a text or film you come across a mention of length in miles, and you need to roughly estimate how much it will be in kilometers, feel free to multiply by 1.5. However, it is also necessary to distinguish the nautical mile, which is used in navigation and aviation - it is slightly longer and is 1852 meters.

Inch

According to legend, the inch was based on the length of the upper phalanx thumb... Of course, there is a difference between a finger and a finger, and therefore 2.54 centimeters is considered the generally accepted value. So if now your child asks how tall Thumbelina was in Andersen's tale, you can answer with accuracy.

Foot

Since a foot is 12 inches, it's pretty easy to calculate the value: 30.48 centimeters. Thus, if you find the value in feet, and you are more used to being aware in meters, then simply divide it by three. For example, the old nautical wish of "a tailwind and seven feet under the keel" meant that 2 meters 10 centimeters should be enough so that the ship would not hit the ground.

Yard

That's three feet, or 91.44 centimeters. Since the yard is only slightly less than a meter, then if you do not need high accuracy, you can not even translate this metric unit. And the name of the famous comedy with Bruce Willis "Nine Yards" now does not seem like an incomprehensible set of letters. (However, in fairness, we note that the name is a phraseological unit and is translated as "everything to the end, without a trace").

Acre

A word that is often used in crosswords and is the answer to the question "English measure of area." Indeed, by an acre, the ancient English meant a piece of land that a couple of bulls cultivate in a day. Equal to an acre exactly 4046.86 square meter, or approximately 1/250 of a square kilometer. You will not envy the pair of bulls who have to cultivate a square kilometer of land - they will have to work for eight whole months!

Lb

Not to be confused with a foot! If a foot means distance, then a pound is the mass of an object. By the way, the pound sterling was originally a pound of silver coins, 453.6 grams, that is, almost a pound. Very often, modern exercise machines such as a bicycle or treadmill suggest entering body weight before starting an exercise. Be careful, because if the simulator is made in England or the USA, then most likely it asks you to indicate the mass in pounds. But that's not a problem - just double your weight in kilograms and tell it to the machine. (But when starting to cook according to old Russian cookbooks, keep in mind that the Russian pound is smaller, only 410 grams.)

Ounce

This is 1/16 of a pound, which is 28.35 grams. It is used in medicine for weighing drugs, as well as in perfumery. Look at the packaging of your perfume - for sure you will find there a 3.3 fl. oz. - this is the designation of the mass (or, more precisely, the volume) of the perfume in ounces.

For most cases, the listed units will be enough, so now you do not have to puzzle over the English designations for length or mass. Simple rules will not only keep you in peace of mind while reading an interesting book that has not been processed by a lazy translator, but also make you more erudite. After all, if a penalty kick in football makes its way from a distance of 12 yards, then it is not so difficult to translate this value into meters, right?

The British metric system brings a lot of inconvenience to those who are used to simple and understandable kilograms, meters and liters. How the mile in km is determined and why the old measure turned out to be so tenacious is described in this article.

Historical measures

From the distant past, inches and miles, pounds and yards, bushels and pints have come to us. All these units of measurement were directly related to humans. Without a standard system of measures and weights at hand, people used what was nearby. And what could be closer own hands and legs? This is how the first anthropometric measures related to the size of human body parts appeared. For example, the length of the phalanx of the index finger was called an inch. A foot is the size of a grown man's foot, and so on. But what is 1 mile? How many kilometers is it?

What are the miles

This well-known measure of length came to us from ancient times. Due to its age, it has many interpretations. When answering the question “1 mile - how many kilometers?”, You should definitely specify which unit of measurement the interlocutor has in mind. The Egyptian mile is 580 meters, and the longest, the Norwegian, is almost 11 kilometers.

Until the middle of the 18th century, there were about 46 different miles in Europe alone, which measured very different distances.

Why is that?

This discrepancy in this standard measure of length is easy to explain. The word "mile" has Latin roots. This standard measure of length was measured by one thousand steps of the ancient Roman legionaries.

After the fall of the Roman Empire, a simple and convenient value was used throughout Europe. Yes, they just considered her differently. Many peoples aligned the mile with their national measures of length. For example, the Russian mile was equal to seven versts, the French equated it with their Gallic leagues, and the British measured the mile in furlongs. The proud Scots also used this measure of length, but it differed significantly in its size in different regions of the Highland and was somewhat longer than the English one.

Snap to geography

Later, with the advent of precision measuring instruments, they tried to standardize the wayward mile. Over the centuries, the study of the surrounding world has given scientists accurate knowledge about the structure of our planet. It turned out to be very convenient to draw the Earth's surface with parallels and meridians and tie the existing units of length to geographic measurements. One of the first in this row was 1 mile. How many kilometers did it take in geographic units? Everything depended on the name.

Such a different mile

Practical Germans were the first to fall in love with such a correspondence. From now on, the German mile (aka geographical) was equal to 1/15 of a degree of the equatorial parallel, which was 7.420 km.

The French divided the land and nautical miles, but equated both values \u200b\u200bto a fraction of the earth's meridian. One land league occupies the 25th part of one degree of the meridian. In the standard system of measures and weights, one French mile is 4.44 km. The nautical mile is slightly longer. The French equated it to 1/20 of the meridian. Accordingly, its length will be greater - the French nautical mile is 5.55 km.

The Swedes did the easiest. Before the spread of the metric system, they used their own mile, which was equal to 10.6 km. After the approval of the international SI system, the Swedes only slightly shortened their mile and recognized it as 10.0 km.

British (American) mile

By far the most widespread is the British mile, often called the American mile. The default for international business documents is the British 1 mile. How many kilometers of air routes are converted into miles for British and American passengers, only employees of international airlines know.

After all, by tradition, the duration of air flights and the bonus for passengers are counted in American miles. One such unit of length is 1.609 km and is a multiple of eight furlongs, 1760 yards and 5280 feet.

More about length and distance

General information

Length is the longest measurement of the body. IN three-dimensional space the length is usually measured horizontally.

Distance is a quantity that determines how far two bodies are from each other.

Distance and length measurement

Distance and length units

In SI, length is measured in meters. Derived quantities such as kilometer (1000 meters) and centimeter (1/100 meter) are also commonly used in the metric system. In countries that do not use the metric system, such as the US and UK, units such as inches, feet and miles are used.

Distance in physics and biology

In biology and physics, lengths are often measured much less than one millimeter. For this, a special value is adopted, a micrometer. One micrometer is equal to 1 × 10⁻⁶ meters. In biology, micrometers measure the size of microorganisms and cells, and in physics, the length of infrared electromagnetic radiation. The micrometer is also called the micron and is sometimes, especially in English-language literature, denoted by the Greek letter µ. Other derivatives of the meter are also widely used: nanometers (1 × 10⁻⁹ meters), picometers (1 × 10⁻¹² meters), femtometers (1 × 10⁻¹⁵ meters and attometers (1 × 10⁻¹⁸ meters).

Navigation distance

In shipping, nautical miles are used. One nautical mile is equal to 1852 meters. It was originally measured as an arc of one minute along the meridian, that is, 1 / (60 × 180) meridian. This made it easier to calculate latitude, since 60 nautical miles equals one degree of latitude. When distance is measured in nautical miles, speed is often measured in nautical knots. One sea knot equal to speed movements of one nautical mile per hour.

Distance in astronomy

In astronomy, long distances are measured, so special quantities are adopted to facilitate calculations.

Astronomical unit (a. e., au) is equal to 149,597,870,700 meters. The magnitude of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is at a distance of one astronomical unit from the Sun.

Light year is equal to 10,000,000,000,000 or 10¹³ kilometers. This is the distance that light travels in a vacuum in one Julian year. This value is used in popular science literature more often than in physics and astronomy.

Parsec is approximately equal to 30,856,775,814,671,900 meters or approximately 3.09 × 10¹³ kilometers. One parsec is the distance from the Sun to another astronomical object, such as a planet, star, moon, or asteroid, at an angle of one arc second. One arc second is 1/3600 of a degree, or approximately 4.8481368 mrad in radians. Parsec can be calculated using parallax - the effect of a visible change in body position, depending on the point of view. During measurements, a segment E1A2 (in the illustration) is laid from the Earth (point E1) to a star or other astronomical object (point A2). Six months later, when the Sun is on the other side of the Earth, a new segment E2A1 is laid from the new position of the Earth (point E2) to a new position in space of the same astronomical object (point A1). In this case, the Sun will be at the intersection of these two segments, at point S. The length of each of the segments E1S and E2S is equal to one astronomical unit. If we put a segment through point S, perpendicular to E1E2, it will pass through the point of intersection of segments E1A2 and E2A1, I. The distance from the Sun to point I is segment SI, it is equal to one parsec when the angle between segments A1I and A2I is two arc seconds.

On the picture:

A1, A2: apparent position of the star
E1, E2: Earth position
S: position of the sun
I: intersection point
IS \u003d 1 parsec
∠P or ∠XIA2: parallax angle
∠P \u003d 1 arc second

Other units

League is an obsolete unit of length previously used in many countries. It is still used in some places, such as in the Yucatan Peninsula and in rural Mexico. This is the distance that a person travels in an hour. Nautical League - three nautical miles, approximately 5.6 kilometers. Lie is a unit roughly equal to a league. IN english language both leagues and leagues are called the same, league. In literature, le is sometimes found in the titles of books, such as "20,000 Leagues Under the Sea" - the famous novel by Jules Verne.

Elbow - the old value, equal to the distance from the tip of the middle finger to the elbow. This value was widespread in the ancient world, in the Middle Ages, and until modern times.

Yard used in British imperial units and equal to three feet or 0.9144 meters. In some countries, such as Canada, where the metric system is adopted, yards are used to measure the fabric and length of swimming pools and sports fields and fields such as golf and soccer.

Definition of meter

The definition of the meter has changed several times. The meter was originally defined as 1 / 10,000,000 of the distance from the North Pole to the equator. Later, the meter was equal to the length of the platinum-iridium standard. Later, the meter was equated to the wavelength of the orange line of the electromagnetic spectrum of the krypton atom ⁸⁶Kr in vacuum, multiplied by 1,650,763.73. Today, the meter is defined as the distance traveled by light in a vacuum in 1/299 792 458 seconds.

Calculations

In geometry, the distance between two points, A and B, with coordinates A (x₁, y₁) and B (x₂, y₂) is calculated by the formula:
