How it works

Every speed is converted through metres per second. The implementation uses 1 km/h = 1/3.6 m/s, 1 mph = 0.44704 m/s, 1 ft/s = 0.3048 m/s and 1 knot = 1,852/3,600 m/s.

Assumptions & limits

  • Uses fixed definitional conversion factors; no intermediate rounding is performed by the converter.
  • Converts scalar speed only; it does not represent direction, acceleration or travel time.
