MachSpeedCalc

Convert between Km/h or Miles/h and Mach speeds in different programming languages.

Mach Number

Ratio of true airspeed to speed of sound in surrounding fluid (which varies as square root of absolute temperature). Mach 1 equals the speed of sound, which is 340.294 meters per second or 761.59 mph at sea level.

The Mach number depends on the speed of sound in the gas and the speed of sound depends on the type of gas and the temperature of the gas.

For the purposes of this software the gas is assumed to be common air.

Default air temperature is the global average temperature at ground level.
