The metre was originally defined as one ten-millionth of the distance from the North Pole to the equator, at sea level along the meridian that passed through Paris.

Unfortunately, improvements in metrology meant that a measure that was meant to be a standard was not constant! So, in 1983 it was re-defined as the distance travelled by light in vacuum in 1/299,792,458 of a second
