metre

1 (US), meter
1. a metric unit of length equal to approximately 1.094 yards
2. the basic SI unit of length; the length of the path travelled by light in free space during a time interval of 1/299 792 458 of a second. In 1983 this definition replaced the previous one based on krypton-86, which in turn had replaced the definition based on the platinum-iridium metre bar kept in Paris FORMULA

metre

(unit)
(US "meter") The fundamental SI unit of length.

From 1889 to 1960, the metre was defined to be the distance between two scratches in a platinum-iridium bar kept in the vault beside the Standard Kilogram at the International Bureau of Weights and Measures near Paris.

This replaced an earlier definition as 10^-7 times the distance between the North Pole and the Equator along a meridian through Paris; unfortunately, this had been based on an inexact value of the circumference of the Earth.

From 1960 to 1984 it was defined to be 1650763.73 wavelengths of the orange-red line of krypton-86 propagating in a vacuum.

It is now defined as the length of the path traveled by light in a vacuum in the time interval of 1/299,792,458 of a second.
