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).

Knot (kn)

Definition

The knot (symbol: kn or kt) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 0.51444 m/s). It is established based on the length of one minute of latitude on a meridian.

Current Use

The knot is used worldwide in meteorology, and in maritime and air navigation. For example, a vessel traveling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour.
