Refers to a Mach number, or the ratio of the speed of an airplane to the speed of sound in the same atmospheric conditions. It is also used as a speed unit. The speed of sound, or Mach 1, is equal to 340.5 m/s, 661 knots, 761 miles per hour, or 1225.5 km/h at sea level under standard conditions, and it decreases with altitude. Above the tropopause (about 36,090 ft, or 11 km), Mach 1 is 295.5 m/s, 574 knots, 658 miles per hour, or 1063.2 km/h. Named after Ernst Mach (1838–1916).
