To convert knots to Mach, enter the value in the first field. The result in Mach is calculated automatically using the exact conversion factor.
1 kn ≈ 0.00151178243394 Mach
1 Mach ≈ 661.470842333 kn
Formula: Mach ≈ kn × 0.00151178243394
kn ≈ Mach × 661.470842333
Definitions: 1 kn = 463/900 m/s; 1 Mach = 340.29 m/s
The knot (kn) is one nautical mile per hour, exactly 1.852 km/h. It is the standard unit of speed in maritime and air navigation and for wind speed at sea.
Mach is speed relative to the speed of sound. This converter uses Mach 1 = 340.29 m/s, the speed of sound in dry air at sea level and 15 °C (standard atmosphere); the real speed of sound changes with temperature and altitude, so the result is exact only under those conditions.
