Here, the velocitiers in different scales can be converted.
Just enter the value, unit and confirm using 'OK '.


Metric: 1m/s  metre per second
3.6km/h  kilometre per hour
Anglo-American: 2.237mph  miles per hour
196.85LFM  feet per minute
Nautic: 1.944kn  knots
Planck: 3.336⋅10-9c  speed of light


Metric system: In SI units, the speed is specified as 'meters per second' (m/s). In everyday use, however, often the unit 'kilometer per hour' (km/h) is more comprehensible.

Anglo-American system: Here for velocities the unit 'miles per hour' (mph) is used. To specify velocities of air in aircraft and technics the unit 'Linear Feet per Minute' (LFM) is common.
It is: 1 mph = 0.44704 m/s and 1 LFM = 0.00508 m/s.

Nautic system: In shipping the velocity is given in the unit 'sea miles per hour', called knots (kn)
It is: 1 kn = 0.5144 m/s.

Planck system: Velocities for systems, in which relativistic effects play a significant role, are expressed as fractions of the speed of light c. This is the maximal velocity with which information can be transmitted. This means that all material particles, but light itself as well, can not go faster than c = 299792458 m/s.
