Yard: A Unit of Length

A yard is a unit of length that is equal to 3 feet or 36 inches in the imperial and U.S. customary systems of measurement. It is also equal to 0.9144 meter in the International System of Units (SI). A distance of 1,760 yards is equal to 1 mile. The symbol for yard is yd.

How to Convert Yard

To convert a yard to other units of length, you can use the following formulas:

  • To convert a yard to feet, multiply by 3. For example, 5 yd = 5 x 3 ft = 15 ft.
  • To convert a yard to inches, multiply by 36. For example, 5 yd = 5 x 36 in = 180 in.
  • To convert a yard to meters, multiply by 0.9144. For example, 5 yd = 5 x 0.9144 m = 4.572 m.
  • To convert a yard to centimeters, multiply by 91.44. For example, 5 yd = 5 x 91.44 cm = 457.2 cm.
  • To convert a yard to millimeters, multiply by 914.4. For example, 5 yd = 5 x 914.4 mm = 4572 mm.
  • To convert a yard to kilometers, divide by 1093.6133. For example, 5 yd = 5 / 1093.6133 km = 0.00457 km.

Where Yard is Used

The yard is mainly used in the United States, the United Kingdom and some other countries that have historical ties with them. It is used for measuring length, distance, area and volume in various contexts such as:

  • Sports: The yard is used for measuring the length of a football field (100 yd), the width of a soccer field (70 yd), the height of a basketball hoop (10 ft or 3.33 yd) and the distance between bases in baseball (90 ft or 30 yd).
  • Textiles: The yard is used for measuring the length of fabrics and yarns (e.g., a yard of cloth, a skein of yarn).
  • Construction: The yard is used for measuring the dimensions of buildings and structures (e.g., a yardstick, a cubic yard of concrete).
  • Transportation: The yard is used for measuring the speed and distance of vehicles (e.g., miles per hour, yards per second).

Definition of the Yard

The current definition of the yard was established by an international agreement in 1959 as exactly 0.9144 meter. This definition was based on a prototype bronze bar that was forged in 1855 as an exact copy of the British Imperial Standard Yard held by Parliament. The prototype bar was called Bronze Yard No.11 and was the official standard of length for the United States until 1892.

The yard is defined as the length of the path travelled by light in vacuum during a time interval of

(1/299792458) × (3600/3937)

seconds. This means that one yard is equal to 3600/3937 light seconds.

History of the Yard

The origin of the yard measure is uncertain. It may have derived from the old English unit of tax assessment called the yardland, which was equal to 1/4 hide or about 30 acres. It may also have derived from the old English unit of surveying called the rod, which was equal to 1/4 chain or about 16 (1/2) feet.

The word “yard” comes from the old English word “gerd” or “gyrd”, which meant a branch, a staff or a measuring rod. The word “yard” was first used to describe this length in William Langland’s poem Piers Plowman in the late 14th century.

The first official standard for the yard was established by King Henry I of England in the early 12th century. He ordered that the yard should be equal to the length of his arm from the tip of his nose to the end of his thumb.

The yard was also used in other countries, such as Scotland, Ireland, France and Spain, with slight variations in length. For example, the Scottish yard was equal to 37 inches, the Irish yard was equal to 40 inches, the French yard was equal to 39.37 inches and the Spanish yard was equal to 32.38 inches.

The yard underwent several changes and refinements over the centuries, until it was finally standardized as 0.9144 meter in 1959 by an international agreement between the United States, the United Kingdom, Canada, Australia, New Zealand and South Africa.

Example Conversions of Yard to Other Units

Here are some example conversions of yard to other units of length:

  • 1 yd = 3 ft
  • 1 yd = 36 in
  • 1 yd = 0.9144 m
  • 1 yd = 91.44 cm
  • 1 yd = 914.4 mm
  • 1 yd = 1/1093.6133 km
The yard is equal to 36 inches or 3 feet.

Angstrom: A Small Unit of Length Used in the SI System

The angstrom is a unit of length that is equal to 0.1 nanometer (nm) or 10-10 meter (m). It is one of the non-SI units that are accepted for use with the International System of Units (SI), which is the most widely used system of measurement in the world. The symbol for angstrom is Å, a letter of the Swedish alphabet. The unit is named after the Swedish physicist Anders Jonas Ångström (1814-1874), who was a pioneer in the field of spectroscopy. The angstrom is often used in the natural sciences and technology to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation, and dimensions of integrated circuit parts. In this article, we will explore the definition, history, usage and conversion of the angstrom as a unit of length.

Definition of the Unit

The angstrom is a unit of length that is equal to 0.1 nanometer (nm) or 10-10 meter (m). It is one of the non-SI units that are accepted for use with the International System of Units (SI), which is based on seven base units: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance) and candela (luminous intensity). The SI base unit of length is the meter, which is defined as the length of the path travelled by light in vacuum during a time interval of 1/299792458 seconds.

The definition of the angstrom has not changed since its introduction in 1868 by Anders Jonas Ångström, who used it to express wavelengths of light in his chart of the spectrum of sunlight. However, the definition of the meter has changed several times over time, as different standards and methods of measurement were adopted by various countries and regions. The current definition of the meter as based on the speed of light was agreed upon by an international treaty in 1983, and since then the angstrom has been exactly equal to 10-10 meter.

History of the Unit

The origin of the angstrom as a unit of length can be traced back to 1868, when Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight, in which he expressed the wavelengths of electromagnetic radiation in multiples of one ten-millionth of a millimeter (or 10-7 mm). He chose this unit because it was convenient for his work on spectroscopy, which is the study of how matter interacts with electromagnetic radiation. He also named this unit after himself, as he wrote in his paper: "I have taken as unit for these measurements one ten-millionth part [of a millimeter], which I will call an Ångström".

Ångström’s unit was soon adopted by other spectroscopists and physicists, who found it useful for expressing wavelengths of visible light, ultraviolet light and X-rays. However, they soon realized that the definition of the millimeter at the time, based on a material artifact, was not accurate enough for their work. So, around 1907 they defined their own unit of length, which they called "Ångström", based on the wavelength of a specific spectral line emitted by krypton-86 gas. This new definition was more precise and stable than the previous one based on the millimeter.

In 1960, when the meter was redefined as based on a specific number of wavelengths emitted by krypton-86 gas, the angstrom became again equal to 10-10 meter. However, this definition was soon replaced by another one based on the speed of light in vacuum in 1983. Since then, the angstrom has remained unchanged as equal to 10-10 meter.

Usage of the Unit

The angstrom is a unit of length that is often used in the natural sciences and technology to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation, and dimensions of integrated circuit parts. Some examples of where the angstrom is used are:

  • Chemistry: The angstrom is used for measuring atomic radii, bond lengths and interatomic distances. For example, a carbon atom has an atomic radius of about 0.77 Å, a carbon-carbon single bond has a length of about 1.54 Å, and a benzene molecule has a diameter of about 5.4 Å.
  • Biology: The angstrom is used for measuring molecular structures, such as proteins, DNA and viruses. For example, a typical amino acid has a size of about 3 Å, a DNA helix has a diameter of about 20 Å, and a coronavirus has a diameter of about 120,000 Å.
  • Physics: The angstrom is used for measuring wavelengths of electromagnetic radiation, such as visible light, ultraviolet light and X-rays. For example, the visible spectrum ranges from about 4000 Å (violet) to 7000 Å (red), the ultraviolet spectrum ranges from about 10 Å to 4000 Å, and the X-ray spectrum ranges from about 0.01 Å to 10 Å.
  • Engineering: The angstrom is used for measuring dimensions of integrated circuit parts, such as transistors, wires and gates. For example, the smallest feature size of a modern microprocessor is about 50 Å.

How to Convert

The angstrom can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert angstroms to other units of length in the U.S. customary system, the imperial system and the SI system:

  • To convert angstroms to inches, divide by 2.54 × 108. For example, 100 Å = 100 / (2.54 × 108) = 3.937 × 10-7 in.
  • To convert angstroms to feet, divide by 3.048 × 109. For example, 1000 Å = 1000 / (3.048 × 109) = 3.281 × 10-8 ft.
  • To convert angstroms to yards, divide by 9.144 × 109. For example, 10,000 Å = 10,000 / (9.144 × 109) = 1.094 × 10-8 yd.
  • To convert angstroms to miles, divide by 1.609 × 1013. For example, 100 million Å = 100 million / (1.609 × 1013) = 6.214 × 10-6 mi.
  • To convert angstroms to centimeters, divide by 108. For example, one angstrom = one / (108) = one-hundred-millionth of a centimeter.
  • To convert angstroms to meters, divide by 1010. For example, one angstrom = one / (1010) = one-ten-billionth of a meter.
