What element was used to redefine a meter?
The element used to redefine a meter was the speed of light. Specifically, the meter was redefined in 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second.
How was the length of a meter redefined in the year 1983?
On October 20, 1983, the meter was officially redefined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second.Light travels at 299792.458 km/sec, so the period was chosen as 0.00000000335641 second, or 3.35641 x 10-9 second.The original definitions (1799 and 1899) depended on a measured standard bar. In 1960, it was redefined as a relationship to the wavelength of light from ions of the element krypton. In 1980, the standard was based on the unusually cohesive wavelength of an iodine-stabilized helium-neon laser.
How was the first meter measured?

What problems are there in maintaining and using a metal bar as the primary length standard as was done before the meter redefined in 1983?
Dimension change due to temperature fluctuation (expansion and contraction) would be one.
