Feet per Second to Speed of Sound Air Converter
CommonMeters per second, km/h, mph and more.
How to convert Feet per Second to Speed of Sound Air
Multiply the feet per second value by 0.00088863: 1 ft/s = 0.00088863 Mach 1. Going the other way, 1 Mach 1 = 1,125.33 ft/s, so divide by 0.00088863 or use the Speed of Sound Air to Feet per Second converter.
About these units
Feet per Second (ft/s)
Feet per second is used for projectile speeds and some engineering calculations. 1 ft/s is exactly 0.3048 m/s, and 60 mph is 88 ft/s.
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.
