About Metres Per Second To Kilometres Per Hour Calculator

Converting Metres per second to Kilometres per hour is one multiplication: a single m/s is 3.6 km/h, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. There are 3,600 seconds in an hour and 1,000 metres in a kilometre, so the factor is 3600/1000 = 3.6 exactly.

Formulas

Metres per second → Kilometres per hour

km/h = m/s × 3.6

Kilometres per hour → Metres per second

m/s = km/h ÷ 3.6

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
