About the units
Mach (Ma)
The speed of sound depends on air temperature. This converter uses the International Standard Atmosphere value at sea level, 15 °C: about 340.29 m/s (1,225 km/h, 761 mph). Mach depends on air temperature; this uses the ISA sea-level speed of sound, 340.29 m/s (15 °C).
Mile per hour (mph)
Exactly 0.44704 m/s. Used for road speeds in the US and UK; 60 mph is about 96.6 km/h.
