Mach number (Ma or M) is the speed of an object moving in air, divided by the speed of sound at that particular conditions, including temperature and pressure. At Standard Sea Level and temperature 15 degrees Celsius, the speed of sound is 761.2 miles per hour (mph) = 340.3 meters per second (m/s) = 1225 kph = 1116 foot per second (ft/s) = 661.5 knots (kn, kt or kts). The speed of sound is equal to 678 mph at temperature -48 degrees F and altitude 30000 feet . 1 mile per hour (mph) = 0.44704 meter per second (m/s) = 1.609344 kilometer per hour (kph) = 1.46666667 foot per second (fps, ft/s) = 0.868976242 knots (kn, kt or kts).
