The metre per second is an SI derived unit of both speed (scalar quantity) and velocity (vector quantity (which have direction and magnitude)), equal to the speed of a body covering a distance of one metre in a time of one second.
The SI unit symbols are m/s, m·s−1, m s−1, or m/s,[1] sometimes (unofficially) abbreviated as mps.[citation needed]
Conversions
1 m/s is equivalent to:
- = 3.6 km/h (exactly)[2]
- ≈ 3.2808 feet per second (approximately)[3]
- ≈ 2.2369 miles per hour (approximately)[4]
- ≈ 1.9438 knots (approximately)[5]
1 foot per second = 0.3048 m/s (exactly)[6]
1 mile per hour = 0.44704 m/s (exactly)[7]
1 km/h = 0.27 m/s (exactly)[8]
Relation to other measures
The benz, named in honour of Karl Benz, has been proposed as a name for one metre per second.[9] Although it has seen some support as a practical unit,[10] primarily from German sources,[9] it was rejected as the SI unit of velocity[11] and has not seen widespread use or acceptance.[12]
Unicode character
