### What is the Metre?

The metre (or meter; US spelling) is the SI base unit of length and uses the symbol m.

Originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole but was redefined in 1799 in terms of a prototyped metre bar (this bar was changed again in 1889).
