CommonMeters per second, km/h, mph and more.
How to convert Kilometers per Second to Mach Number
Multiply the kilometers per second value by 2.91545: 1 km/s = 2.91545 M. Going the other way, 1 M = 0.343 km/s, so divide by 2.91545 or use the Mach Number to Kilometers per Second 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.
