The metre per second (American English: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.

The SI unit symbols are m·s−1, m s−1, m/s, or m/s,[1] sometimes (unofficially) abbreviated as mps.

## 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]

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]
