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