Unit Information

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).

Kilometer per hour (km/h)

Definition

The kilometer per hour (symbol: km/h) is a unit of speed, expressing the number of kilometers traveled in one hour. One kilometer per hour is equivalent to approximately 0.27778 meters per second or 0.62137 miles per hour.

Current Use

Kilometers per hour is the most common unit used for road speed limits and vehicle speeds in most of the world where the metric system is adopted. It is also used in rail transport and general travel measurements in most countries.
