How to convert Speed of Sound Air to Kilometers per Second
Multiply the speed of sound air value by 0.343: 1 Mach 1 = 0.343 km/s. Going the other way, 1 km/s = 2.91545 Mach 1, so divide by 0.343 or use the Kilometers per Second to Speed of Sound Air converter.

Speed of Sound Air (Mach 1)
The speed of sound in air at 20 °C is about 343 meters per second (1,235 km/h). It falls as the air gets colder, so the exact value depends on conditions.
