Mach (Ma) to Kilometers per hour (km/h) Conversion
Mach
The Mach number represents the ratio of an object's speed to the local speed of sound. Mach 1 is approximately 343 m/s (1,235 km/h) at sea level and 20 °C, but varies with temperature and altitude. Named after Austrian physicist Ernst Mach, the Mach number is fundamental in aerodynamics: subsonic is below Mach 0.8, supersonic from Mach 1.2 to 5, and hypersonic above Mach 5.
Kilometers per hour
Kilometres per hour (km/h) is the standard unit for expressing speed in road transport, meteorology, and everyday life in all metric-system countries. Converting km/h to metres per second requires dividing by 3.6. Average human walking speed is approximately 5 km/h, highway speed limits range from 100 to 130 km/h, and commercial aircraft cruise at approximately 900 km/h.
