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 meter was redefined in 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second. This redefinition was based on the speed of light, providing a more precise and universal measurement standard for the meter.
