English units of measure. Controversial question: how much is a foot? Everywhere is different

An inch (from the Dutch. duim - thumb) is a unit of distance, the exact linear value of which varies in different countries. Usually, an inch is understood as the so-called "international", or "English" inch, which since 1958 has been tied to the metric SI system.

Foot (English foot - foot) is a unit of distance, the exact linear value of which, like inches, varies in different countries. Usually, a foot is understood as the so-called "international" or "English" foot, which is equal to 12 inches, since 1958 it has been tied to the metric SI system.

In English units, 1 inch = 1/12 foot = 1/36 yard.

Thus, at present, the following is understood by the values ​​\u200b\u200bof an inch and a foot:

• 1 inch = 2.54 cm
• 1 foot = 12 inches = 0.3048 meters

Designation

In modern Russian, there is no generally accepted letter abbreviation for inches. Before the transition to the metric system, the abbreviation "dm" was used, but now decimeters are designated as such. Most often, the English designation is copied: the same double stroke as in the designation of arc seconds, placed without a space after the numerical value, for example: 3 ″ (3 inches). In English-speaking countries, the abbreviation "in" is also used (from the English inch - inch).

In modern Russian, there is no generally accepted letter abbreviation for feet, as well as inches. The English designation is most often copied: the foot is designated as a single stroke, as in the designation of minutes of arc, placed without a space after the numerical value, for example: 3′ (3 feet). In English-speaking countries, the abbreviation "ft" is also used (from the English foot - foot, foot).

Origin

It is generally believed that the inch was originally defined as the length of the top joint of the king's thumb. According to other sources, an inch was defined as 1/36 of a yard, which, in turn, was established by King Henry I of England in 1101 as the distance between the tip of the nose and the thumb of his outstretched hand. The "legal" inch called inch (inch) was approved by King Edward II in 1324 as the length of three barley grains taken out of the middle part of the ear and put one to the other with their ends. In English life, and now the measure "barley grain", equal to one third of an inch, is used. It is important to note here that it is correct to designate inches as whole numbers and ordinary, and not decimal fractions.

Later, in the 16th century, the "legitimate" English foot appeared. It was defined as 1/16 of the total length of the left feet of sixteen people coming out of Matins on Sunday. With the help of this very ingenious and far-sighted technical solution for its time, it was always possible to determine the foot relatively accurately, since the feet of sixteen people randomly selected from all those who gathered on Sunday for prayer, of course, had very different lengths. By the way, the idea of ​​the need for an average approach to improve the accuracy of determining the foot was used in the 16th century by the mathematician Clavius, known as the creator of the Gregorian calendar. He proposed to calculate the geometric, that is, especially precise (for many years all mathematics was called geometry) foot as the total width of sixty-four barley grains. This sharply increased the accuracy of reproduction of the foot value.

What is "foot"

A non-system block that is not part of the SI system.

In Russia, legs are used at SI stations in aviation. Foot (ft, ft, ') from the English word foot-foot. This unit of measure is in the English system of measures. It was merged in 1958, this time with an "international" corollary of 0.3048 m.

In addition to the international leg, which is 30.48 cm, there are Amsterdam (11 inches), Britannia, Baden, Warsaw, Danube, Greece, etc. In Russia, 1/7 legs have been saturated.

What is "centimeter"

Centimeter (cm cm) is a unit of length in SI engines gravitational metric system, MKS and MTS sub m. This unit is also used to measure certain electrical and magnetic parameters (capacitance, inductance, friction rolling coefficient, wavelength, mean free center, optical path, focal length, Compton wavelength, de Broglie wavelength, etc.).

The foot is the basic unit used to measure length in the English system. Its important difference from many other quantities is that in different countries of the world the length of a foot has always been very different. Only in 1958, in English-speaking countries, units of length were unified. This made it easier to convert feet to meters, but many still wonder how many meters are in a foot?

Often, the question of what a foot in meters is equal to is asked by people studying foreign languages, as they have to regularly deal with an unusual measure of length in scientific articles, news publications and fiction. At the same time, feet are different - English, Russian, Roman.

How did the foot get its name?

If you studied English at school or college, you know that the word foot is translated from English as a foot. It can be assumed that the length of a foot coincides with the length of a human foot.

But how can this be, if everyone has a different foot length? The fact is that many years ago there were no exact measures for measuring length, so people used the proportions of their own bodies. Of course, this is not the most accurate measurement, but it suited everyone and coped with its function. On average, the length of an adult foot is 28-30 cm, which is approximately comparable to a foot, but we will return to the exact parameters.

The history of the appearance of the foot

A unit of measurement called the foot was actively used in English-speaking countries as early as the 16th century. When the term was introduced, it was equated to the width of 64 grains of barley. Another meaning of the measure was also associated with agriculture - the plowman's stick, which varied in length from 12 to 16 feet.

In Russia, feet were also used, and they appeared during the reign of Peter I and one foot was equated to 12 inches. Also in those years, shipbuilding in Russia was actively developing, so it was necessary to somehow connect Russian measures of length with English ones. Everything was resolved quite simply: 1 sazhen was equal to 7 feet.

In Europe, the foot was usually measured by the length of 12 fingers, and even earlier the length of the foot was used. In general, the foot appeared in ancient Egypt, and the Romans and Greeks popularized this measure. Sometimes the length of three palms was used to determine the length of a foot. Of course, today the conversion of feet to meters is carried out according to a more accurate system, and there are also convenient tables.

The use of feet in Russia

In English-speaking countries, feet are used in the same way as meters in Russia, but in our country, feet are also common in certain areas. An off-system unit of measurement is used in the Russian Federation in aviation for:

• flight altitude determination;
• descent rate calculation;
• determining the rate of ascent of the aircraft.

In 2009, the Russian government approved a decree in which the foot was recognized as a unit of measurement, and a single stroke is used for designation - ‘. Pilots have no difficulty converting feet to meters, and in most cases there is no need for this at all.

How many meters are in a foot?

The exact value of feet in terms of meters was determined only in 1958 at a special conference that brought together participants from many English-speaking countries. After the debate, the length of 1 foot in meters was unified - it amounted to 0.3048 m. Below we will consider a table that simplifies the translation of 1, 10, 25, 50 feet into meters and vice versa, so you will understand everything.

Some are interested in a more complex question - how many square meters in a square foot? It is calculated by all standard formulas, so it turns out that:

• one square meter is equal to 10.76 square meters. feet;
• in every square foot 0.093 sq. m.

You can remember these ratios or calculate each time using standard mathematical formulas. In general, square or cubic feet are extremely rarely converted to square meters, and more often a translation of length from one system of measurement to another is required. The table will help you figure out how to convert feet to meters:

Also, to complete the picture, we propose to visually consider how meters are converted to feet. The situation is the opposite of converting feet to meters, but the table reflects all the ratios:

The International System of Units (SI) was developed for the convenience of translating various measures and quantities into understandable values ​​for all. The meter was recognized as the standard for length. But in some countries distances are still measured in miles, yards, feet and inches. Is it convenient? And how, for example, to find out how many meters are in a foot?

Measure of length

People's lives are a series of changing time periods in which one cannot stay in one place all the time. To account for work, time, distances, a comparative system of units is required. In each country, it was invented based on the traditions, features and realities of the area. When the need arose to develop foreign trade relations, they thought about introducing common standards for measuring quantities.

Length is one of the most important physical quantities. In the old days in Russia, it was customary to measure height in elbows and spans, in arshins and vershoks, and since the time of Peter I - in feet and inches. For most of us, these quantities are not familiar. How many meters in a foot, not everyone knows. Let's try to figure out why the metric system was not introduced in some countries?

Foot and meter: history

It is difficult to say where these names came from. With foot (English foot) is clearer: the word is translated as foot. According to one version, this measure arose in the old days when measuring the feet. They say that once sixteen people leaving the temple in the morning after the service were measured in this way. Adding the total length of their left feet and dividing by 16, we found out the average value, which was recognized in those days as the standard of distance. It remains to be seen how it is now determined how many meters are in a foot.

There have been many attempts to bind the value to some meaningful and constant value. Meter (metre from French and metrum from Latin) is defined as a measure. Once it was calculated as one forty-millionth part of the meridian on the longitude of Paris. Now this value is standardized and is defined as the distance traveled by a particle of light in vacuum in a time interval that is a multiple of 1/299,792,458 of a second.

At one time, Napoleon conquered almost all of Europe, with the exception of Great Britain. In France, the meter was already in use at that time. In the occupied territories, with his arrival, new standards and rules spread. England at that time did not support such innovations, did not submit to Napoleon, and therefore left the traditional system of calculation on its territory (1 yard \u003d 3 feet \u003d 36 inches).

Almost all non-systemic distance units are tied to the international system by rigid coefficients. But there are times when you have to translate one value into another. Such situations arise when it comes to the values ​​used in English-speaking countries, mainly the US and the UK. In Canada, too, although the metric system is in effect, golf courses, football courses, swimming pool paths and fabric cuts in the old fashioned way are still measured in yards.

The length of a foot in meters (in international units) is defined as the derivatives of X and a factor. For example, what needs to be done to determine how many meters are in 1000 "(foot indicated by a dash). It is necessary to multiply this number by the indicated coefficient: 1000 × 0.3048 \u003d 304.8 m. Accordingly, 1 meter is equal to 0.3048 m.

The reverse conversion of feet to meters is carried out using a coefficient of 3.2808 (for more accurate calculations, 3.28083989501312). Divide the desired value of X in feet by this number and get the value in meters. For example, 1′ / 3.2808 = 0.3048 m.

Convenient measurements

Now there are no problems with accurate measurement of distances. But if there is no ruler or tape measure at hand, knowledge of individual “live measurements” may come in handy. What is meant? Even without knowing how many meters are in a foot, you can easily calculate the distance using measurements of your body parts. If you measure the length of the arm from the fingertips to the elbow in advance and remember the value, then you can, if necessary, operate with a primitive half-meter measure.

The maximum distance between arms extended to the sides (flying fathom) is almost always the height of a person. There are a number of other divisors: the width of the palm, the greatest length of the segment between the thumb and middle finger, between the index and middle when spreading them apart. You can choose any other landmark and use it with confidence if necessary. For reference: inch - 2.54 cm, foot - 30.48 cm, yard - 91.44 cm.
