Mach (Ma) to Miles per hour (mph) Conversion
Mach
The Mach number represents the ratio of an object's speed to the local speed of sound. Mach 1 is approximately 343 m/s (1,235 km/h) at sea level and 20 °C, but varies with temperature and altitude. Named after Austrian physicist Ernst Mach, the Mach number is fundamental in aerodynamics: subsonic is below Mach 0.8, supersonic from Mach 1.2 to 5, and hypersonic above Mach 5.
Miles per hour
Miles per hour (mph) is the unit of speed used in road transport in the United States, United Kingdom, and a small number of other countries. One mile per hour equals approximately 1.60934 km/h or 0.44704 m/s. Speed limits on US interstate highways are commonly 65–75 mph, while the UK national speed limit is 70 mph.
