Meter Definition

The meter is the basic unit of length in the International System of Units, and the symbol is m. One meter is equivalent to 1.09361329834 yards. It can be used to measure length, width and height.

The definition of “meter” originated in France. The length of 1 meter was originally defined as one ten-millionth of the distance from the Earth’s equator to the North Pole on the meridian passing through Paris. With the deepening of people’s understanding of metrology, the definition of the length of the meter has been revised several times. From May 20, 2019, the definition of meter is updated to: when the speed of light c in vacuum is expressed in m/s, a fixed value of 299792458 is selected to define the meter.
