Metre (or meter), symbol m, is the base unit of length in the International System of Units (SI). Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole, its definition of has been periodically refined to reflect growing knowledge of metrology. Since 1983, it is defined as the distance travelled by light in a complete vacuum in 1⁄299,792,458 of a second.
