Meter per Second (Speed) (m/s)
The meter per second is the SI unit of speed. Walking is about 1.4 m/s, a sprinter about 10 m/s and sound in air about 343 m/s; multiply by 3.6 for km/h.
Symbol: m/s
Quantity: speed (distance per time)
SI relation: m/s is the coherent SI unit of speed.
Derivation: The SI unit of speed: one metre travelled per second.
Exact: yes, by definition
Typical uses
- Physics problems and science classes
- Wind speed in weather data
- Engineering and sports science
