The metre 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 . According to the definition of metre, [1] 1 m/s is exactly of the speed of light .

The SI unit symbols are m/s , m·s ?1 , m s ?1 , or m / s . [2]

Conversions [ edit ]

1 m/s 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 = 0.3048 m/s (exactly) [7]

1 mile per hour = 0.447 04  m/s (exactly) [8]

1  km/h = 0.2 7  m/s (exactly) [9]

Relation to other measures [ edit ]

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 [ edit ]

The "metre per second" symbol is encoded by Unicode at code point U+33A7 ㎧ SQUARE M OVER S . [14]
