A metre (US spelling, meter) is the basic unit of length in the SI measurement system. According to the earliest definition (dating to the French Revolution), it was 1/10,000,000th (one ten-millionth) of the distance between the Earth's equator and the North Pole along the Paris meridian. The metre is now officially defined as the distance light travels in a vacuum in 1/299,792,458th of a second.

Other commonly used units of length are millimetre (symbol mm, equal to 1/1000 m), centimetre (symbol cm, equal to 1/000 m) and kilometre (symbol km, equal to 1000 m)

1000 mm = 1 m

100 cm = 1 m

1 km = 1000 m

In the Imperial system of measurement, one metre is equal to about 39.37 inches, 3.28 feet, or about 1.09 yards.
