Feet per Second to Mach Number Converter
CommonMeters per second, km/h, mph and more.
How to convert Feet per Second to Mach Number
Multiply the feet per second value by 0.00088863: 1 ft/s = 0.00088863 M. Going the other way, 1 M = 1,125.33 ft/s, so divide by 0.00088863 or use the Mach Number 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.
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.
