History and origin
The metre was defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, later realised as a platinum bar. Since 1983 it has been defined by fixing the speed of light at exactly 299 792 458 metres per second, tying it to a constant of nature rather than an object.
Current use
The metre is the base unit of length across the metric world, used for everything from building plans to sports fields; the United States is the main country that still measures everyday length in feet and inches.
