# LENGTH Units Conversion

## LENGTH UNIT MEASUREMENT

A unit of length refers to any discrete, pre-established length or distance having a constant magnitude which is used as a reference or convention to express linear dimension.

The most common units in modern use are U.S. customary units in the United States and metric units elsewhere. British Imperial units are still used for some purposes in the United Kingdom and some other countries. The metric system is sub-divided into SI and non-SI units.

Commonly used metric system length units; meters, centimeters, millimeters, kilometers.

• 1 meter = 100 centimeters.
• 1 centimeters = 10 millimeters.
• 1 kilometer = 1000 meters.

Commonly used U.S. system length units; inches, feet, miles, yards.

• 1 foot = 12 inches.
• 1 yard = 3 feet.
• 1 mile = 5280 feet.

Length units used to denote distances in the vastness of space, as in astronomy, are much longer than those typically used on Earth and include the astronomical unit, the light-year, and the parsec.
