The French were the first to define the length of a meter by using a alluminium/platinum alloy bar of a meter length at 25 degrees Celcius. This however is very inaccuracte for quantum measurements as the length of the bar would change two much depending on how you hold it. A better measurement found in 1983 is the distance that light travels in a vacuum in 1/229,792,458ths of a second. (for those of us with a decent knowledge of relativity that measurement is taken in the rest frame). Crazy I know but at least this way any body in a good physics lab can reproduce this distance without the use of some silly French rod.
The standard unit of length in the metric system is the meter (m).
The SI standard unit for measuring length is the meter (m).
The standard unit of length in the metric system is the meter: 1 millimeter = 0.001 meter 1 centimeter = 0.01 meter 1 decimeter = 0.1 meter 1 kilometer = 1000 meters
meter
The meter is the standard unit of measurement for length in the SI system.
It was redefined as 3 feet...
50 tds
It was not. The current definition was established in 1983.
Dimension change due to temperature fluctuation (expansion and contraction) would be one.

The Metric Act of 1866 redefined the meter in American terms as 39.37 inches.
they put thangs tew gether nd they brainstormed alot.
