(and now the technical stuff, if you're interested)
The foot or its plural form feet, uses the symbol ft, or often simply the apostrophe '
The meter or metre uses the symbol m
The meter is the SI (International System of Units) base unit of distance. In American English, German, Danish, Swedish, and others
it is spelled meter. In British, Australian, Canadian, French, and others it is spelled metre. Other countries have different spellings
as well including metr, metras, metri, and metro.
Originally the meter was defined as one ten-millionth of the distance from the Earth's equator to the North Pole at sea level,
and later a precisely measured bar was created and used as the definition. Then the 17th General Conference on Weights and Measures
in 1983 defined the meter as the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.
In 1959 the U.S. National Bureau of Standards and the British Weights and Measures Act of 1963 defined the foot at exactly
30.48 centimeters. Prior to that the U.S. Metric Act of 1866 defined the foot as exactly 1200/3937 meters, this is now called
the survey foot.
meter = m
foot = ft or '
feet = ft or '
