More about length and distance
General information
Length is greatest dimension bodies. In three-dimensional space, length is usually measured horizontally.
Distance is a quantity that determines how far two bodies are from each other.
Measuring distance and length
Units of distance and length
In the SI system, length is measured in meters. Derived units such as kilometer (1000 meters) and centimeter (1/100 meter) are also commonly used in the metric system. Countries that do not use the metric system, such as the US and UK, use units such as inches, feet and miles.
Distance in physics and biology
In biology and physics, lengths are often measured at much less than one millimeter. For this purpose, a special value has been adopted, the 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. A micrometer is also called a micron and is sometimes, especially in English 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
Shipping uses nautical miles. One nautical mile is equal to 1852 meters. It was originally measured as an arc of one minute along the meridian, that is, 1/(60x180) of the meridian. This made latitude calculations easier, since 60 nautical miles equaled one degree of latitude. When distance is measured in nautical miles, speed is often measured in knots. One sea knot equal to speed movement of one nautical mile per hour.
Distance in astronomy
In astronomy they measure long distances, therefore, to facilitate calculations, special quantities have been adopted.
Astronomical unit(au, au) is equal to 149,597,870,700 meters. The value of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is located at a distance of one astronomical unit from the Sun.
Light year 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 quantity is used in popular science literature more often than in physics and astronomy.
Parsec 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, with an angle of one arcsecond. One arcsecond is 1/3600 of a degree, or approximately 4.8481368 microrads in radians. Parsec can be calculated using the parallax effect visible change body position, depending on the observation point. When making measurements, lay a segment E1A2 (in the illustration) 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 the 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 plot a segment through point S, perpendicular to E1E2, it will pass through the intersection point 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 arcseconds.

Other units
League- an obsolete unit of length previously used in many countries. It is still used in some places, such as the Yucatan Peninsula and rural areas of Mexico. This is the distance a person travels in an hour. Sea League - three nautical miles, approximately 5.6 kilometers. Lieu is a unit approximately equal to a league. IN English language both leagues and leagues are called the same, league. In literature, league is sometimes found in the title of books, such as “20,000 Leagues Under the Sea” - the famous novel by Jules Verne.
Elbow- ancient value, equal to 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 the British Imperial system and is 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 fabric and the length of swimming pools and sports fields and fields, such as golf and football courses.
Definition of meter
The definition of 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 orange line electromagnetic spectrum of a krypton atom ⁸⁶Kr in a vacuum, multiplied by 1,650,763.73. Today, a meter is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second.
Computations
In geometry, the distance between two points, A and B, with coordinates A(x₁, y₁) and B(x₂, y₂) is calculated by the formula:

Inch (from Dutch duim - thumb) - a unit of measurement of distance, exact linear value which differs in different countries. Usually the inch is understood as the so-called “international” or “English” inch, which since 1958 has been tied to the SI metric system.
Foot (English foot - foot) is a unit of distance measurement, the exact linear value of which, like inches, varies in different countries. Typically, a foot refers to the so-called “international” or “English” foot, which is equal to 12 inches, and since 1958 it has been tied to the SI metric system.
In the English system of measures, 1 inch = 1/12 feet = 1/36 yards.
Thus, at present, the following is understood by the inches and feet:
- 1 inch = 2.54 cm
- 1 foot = 12 inches = 0.3048 meters
Designation
In modern Russian language it is generally accepted letter abbreviation There are no inches to indicate. Before the transition to the metric system, the abbreviation “dm” was used, but now this is how decimeters are designated. Most often the English designation is copied: the same double stroke as in the designation of arc seconds, placed without a space behind 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. Most often, the English designation is copied: a foot is indicated as a single stroke, as in the designation of arc minutes, placed without a space behind 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 upper phalanx 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 the inch, was approved by King Edward II in 1324 as the length of three barley grains taken from the middle part of the ear and placed one end at the other. In English everyday life, the measure “barley grain”, equal to one third of an inch, is still used. It is important to note here that it is correct to denote inches using whole numbers and fractions rather than decimals.
Later, in the 16th century, a “legal” one appeared. English foot. It was defined as 1/16 of the total length of the left feet of the sixteen people leaving Matins on Sunday. With the help of this very witty and far-sighted for its time technical solution It was always possible to determine a foot relatively accurately, since the feet of sixteen randomly selected people from all those who gathered on Sunday for prayer naturally had very different lengths. By the way, the idea of the need for an average statistical 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 calculating a geometric, that is, especially accurate (geometry for many years was the name for all mathematics) foot as the total width of sixty-four barley grains. This dramatically increased the accuracy of reproducing the size of a foot.

What is a "leg"
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 measurement is in the English system of measures. It was unified in 1958, this time with an "international" corollary of 0.3048 m.
In addition to the international foot, which is 30.48 cm, there are Amsterdam (11 inches), Britain, Baden, Warsaw, Danube, Greece, etc. In Russia, 1/7 feet have been saturated.
What is "centimeter"
Centimeter (cm cm) is a unit of length in the SI gravitational metric system, ISS and MTS-sub-m engines. This unit is also used to measure certain electrical and magnetic parameters (capacitance, inductance, rolling coefficient of friction, wavelength, mean free center, length optical path, focal length, Compton wavelength, de Broglie wavelength, etc.).

The meter was later equated to the wavelength of the orange line of the electromagnetic spectrum of the krypton atom ⁸⁶Kr in a vacuum, multiplied by 1,650,763.73. Today, a meter is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second.

More about length and distance
General information
Length is the largest measurement of the body. In three-dimensional space, length is usually measured horizontally.
Distance is a quantity that determines how far two bodies are from each other.
Measuring distance and length
Units of distance and length
In the SI system, length is measured in meters. Derived units such as kilometer (1000 meters) and centimeter (1/100 meter) are also commonly used in the metric system. Countries that do not use the metric system, such as the US and UK, use units such as inches, feet and miles.
Distance in physics and biology
In biology and physics, lengths are often measured at much less than one millimeter. For this purpose, a special value has been adopted, the micrometer. One micrometer is equal to 1×10⁻⁶ meters. In biology, the size of microorganisms and cells is measured in micrometers, and in physics, the length of infrared electromagnetic radiation is measured. A micrometer is also called a micron and is sometimes, especially in English 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
Shipping uses nautical miles. One nautical mile is equal to 1852 meters. It was originally measured as an arc of one minute along the meridian, that is, 1/(60x180) of the meridian. This made latitude calculations easier, since 60 nautical miles equaled one degree of latitude. When distance is measured in nautical miles, speed is often measured in knots. One sea knot equals a speed of one nautical mile per hour.
Distance in astronomy
In astronomy, large distances are measured, so special quantities are adopted to facilitate calculations.
Astronomical unit(au, au) is equal to 149,597,870,700 meters. The value of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is located at a distance of one astronomical unit from the Sun.
Light year 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 quantity is used in popular science literature more often than in physics and astronomy.
Parsec 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, with an angle of one arcsecond. One arcsecond is 1/3600 of a degree, or approximately 4.8481368 microrads in radians. Parsec can be calculated using parallax - the effect of visible changes in body position, depending on the observation point. When making measurements, lay a segment E1A2 (in the illustration) 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 the 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 plot a segment through point S, perpendicular to E1E2, it will pass through the intersection point 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 arcseconds.
On the image:
- A1, A2: apparent star position
- E1, E2: Earth position
- S: Sun position
- I: point of intersection
- IS = 1 parsec
- ∠P or ∠XIA2: parallax angle
- ∠P = 1 arcsecond
Other units
League- an obsolete unit of length previously used in many countries. It is still used in some places, such as the Yucatan Peninsula and rural areas of Mexico. This is the distance a person travels in an hour. Sea League - three nautical miles, approximately 5.6 kilometers. Lieu is a unit approximately equal to a league. In English, both leagues and leagues are called the same, league. In literature, league is sometimes found in the title of books, such as “20,000 Leagues Under the Sea” - the famous novel by Jules Verne.
Elbow- an ancient 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 the British Imperial system and is 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 fabric and the length of swimming pools and sports fields and fields, such as golf and football courses.
