Unit ofspeed

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 it is abbreviated as "mps".[2]


is equivalent to:

= 3.6 km/h (exactly)[3]
? 3.2808 feet per second (approximately)[4]
? 2.2369 miles per hour (approximately)[5]
? 1.9438 knots (approximately)[6]

1 foot per second = (exactly)[7]

1 mile per hour = (exactly)[8]

km/h = (exactly)[9]

Relation to other measures

The benz, named in honour of Karl Benz, has been proposed as a name for one metre per second.[10] Although it has seen some support as a practical unit,[11] primarily from German sources,[10] it was rejected as the SI unit of velocity[12] and has not seen widespread use or acceptance.[13]

Unicode character

The "metre per second" symbol is encoded by Unicode at code point SQUARE M OVER S.[14]
