About miles per hour and mach
The Conversion Formula
To convert miles per hour to mach, multiply the value by the conversion factor: 1 mph = 0.00130332 Ma. For a worked example, suppose you need to convert 25 mph to mach: 25 × 0.00130332 = 0.0325831 Ma. To convert in the opposite direction, divide by 0.00130332, or equivalently multiply by 767.27.
About miles per hour
Miles per hour (mph) is the standard speed unit for the United States and United Kingdom. It has been used since the days of stagecoaches but became codified with the rise of the automobile and the need for speed limits. Despite metrication efforts, the UK retains mph for its roads, keeping it aligned with the US system. miles per hour are commonly used in US & UK Speed limits, Baseball pitch speeds, Tennis serve speeds, and Hurricane wind speeds (US), NASCAR.
US highway speeds are typically 65-75 mph.
About mach
Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Named after Ernst Mach, 'Mach 1' is the speed of sound. It varies with temperature and altitude. It is the language of supersonic flight and high-speed aerodynamics. mach are commonly used in Fighter jets, Rockets and missiles, Supersonic transport, and Space shuttle re-entry, Aerodynamic testing.
A commercial airliner cruises around Mach 0.8.
