The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second. According to the definition of metre,[1] 1 m/s is exactly of the speed of light.
The SI unit symbols are m/s, m·s−1, m s−1, or m/s.[2]
