Mach Number to Kilometers per Second Converter
CommonMeters per second, km/h, mph and more.
How to convert Mach Number to Kilometers per Second
Multiply the mach number value by 0.343: 1 M = 0.343 km/s. Going the other way, 1 km/s = 2.91545 M, so divide by 0.343 or use the Kilometers per Second to Mach Number converter.
About these units
Mach Number (M)
Mach number is speed divided by the local speed of sound; this converter uses 343 m/s, the value in air at 20 °C. Mach 1 at sea level is therefore about 1,235 km/h.
