Unit Information

Mile per hour (mph)

Definition

The mile per hour (symbol: mph) is a British Imperial and United States Customary unit of speed expressing the number of statute miles traveled in one hour. One mile per hour is exactly equal to 1.609344 kilometers per hour.

Current Use

The mile per hour is the standard unit used for speed limits and vehicle speeds on roads in the United States, the United Kingdom, and several other countries. It is also commonly used to express speeds in various sports, such as baseball pitch speeds or cricket bowling speeds.

Mach number (M)

Definition

The Mach number (symbol: M) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Mach 1 represents the speed of sound, which varies with temperature and the medium it travels through.

Current Use

Mach number is used primarily for aircraft and projectiles traveling at high speeds. It helps define flight regimes such as subsonic (M < 1.0), transonic (0.8 < M < 1.2), supersonic (M > 1.0), and hypersonic (M > 5.0).
