Metre per second

Metre per second (U.S. spelling: 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, sometimes (unofficially) abbreviated as "mps". Where metres per second are several orders of magnitude too slow to be convenient, such as in astronomical measurements, velocities may be given in kilometres per second, where 1 km/s is 1000 metres per second, sometimes unofficially abbreviated as "kps".

Conversions

1 m/s is equivalent to:

1 foot per second = 0.3048 m/s (exactly)

1 mile per hour = 0.44704 m/s (exactly)

1 km/h = 0.27 m/s (exactly)

1 kilometre per second is equivalent to:

Relation to other measures

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

Metre per second squared

The metre per second squared is the unit of acceleration in the International System of Units (SI). As a derived unit it is composed from the SI base units of length, the metre, and time, the second. Its symbol is written in several forms as m/s², m·s⁻² or m s⁻², or less commonly, as m/s/s.

As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.

Example

An object experiences a constant acceleration of one metre per second squared (1 m/s²) from a state of rest, when it achieves the speed of 5 m/s after 5 seconds and 10 m/s after 10 seconds.

Related units

Newton's Second Law states that force equals mass multiplied by acceleration. The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg⁻¹, or N/kg.
