Metre per second

The metre per second (alternatively spelled meter 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. As the base unit for speed in the SI, it is commonly used in physics, mechanics, and engineering contexts. It represents both scalar speed and vector velocity, depending on context. According to the definition of metre, 1 m/s is exactly ⁠1/299792458⁠ of the speed of light.

The SI unit symbols are m/s, m·s, m s, or ⁠m/s⁠.
