How to convert

1 yard (yd) = 0.0009144 kilometer (km). Yard (yd) is a unit of Length used in Standard system. Kilometer (km) is a unit of Length used in Metric system.

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.

Kilometer - Unit of Distance / Length

Unit Symbol/Abbreviation: km

Where the unit used in the World:

The kilometer is used as a unit used to measure distances or lengths.
It's a standard measure for travelled distances, geographical distances and maps in most countries excluding the USA and the United Kingdom where mile is still used for this purpose.
between geographical locations on land, and in most countries is the official unit for this purpose. Primary exceptions are the United Kingdom, Liberia, Myanmar and the United States of America, where the mile remains as standard as a part of imperial system.

Definition of the Unit:

The kilometer (kilometre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to one thousand meters.

1 km is equivalent to 0.62137 miles.

History of the Unit:

Although the meter was defined in 1799 in France, the kilometer was first adopted for everyday use by the Dutch in 1817 under local name of the mijl. The myriametre (10000 meters) and "lieues de Poste" (Postal leagues, 4288 meters) were preferred to the "kilometer" for everyday use in France in 19th century. In the mid 19th century the kilometer was already in everyday use in the Italy and in Netherlands and the myriametre was still in use in France. The CIPM (The International Committee for Weights and Measures) officially abolished the prefix "myria-" and the "myriametre" in 1935, leaving the kilometer as the recognised unit of length instead of myriametre.

Where it's used:

The kilometer is commonly used on road signs to indicate the distance to travel to a given location, on maps to indicate scale, for odometer indication in automotive industry. It is also the most popular unit for describing the distance between geographical points and locations.

Equivalents in other units and scales:

  • 1 km = 1000000 millimeters (mm)
  • 1 km = 100 000 centimeters (cm)
  • 1 km = 10000 decimeters (dm)
  • 1 km = 1000 meters (m)
  • 1 km = 3280.84 feet (ft)
  • 1 megameter = 1000 km
  • 1 gigameter = 1000000 km
  • 1 mile = 1.609 km
  • 1 yard = 0.000914 km
  • 1 foot = 0.000305 km
  • 1 inch = 0.0000254 km
  • Units of length in the metric SI system are based on multiples or fractions of a meter.
  • There are measurements of length/distance in the metric SI system greater than a kilometer that can be expressed in terms of kilometres.

1 km is equivalent to 0.621371 mi.

The kilometer is unit of length in the metric SI system and is equivalent to one thousand metres.
