Facts about the Meter
The meter is the SI base unit of length. It is currently defined as the distance light travels in a vacuum in 1/299,792,458 seconds.
Originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, the meter has undergone several refinements. Since 1983, it has been based on the speed of light, making it universally constant and precise.
Meters are used globally in scientific research, construction, transportation, athletics, and everyday applications such as measuring rooms or human height.
