Meters per second (m/s) to Mach (Ma) Conversion
Meters per second
Metres per second (m/s) is the SI coherent derived unit of speed, the preferred unit for speed in physics, engineering, and scientific literature worldwide because it integrates directly into SI equations. The speed of sound at 20 °C is approximately 343 m/s, human sprinting speed approaches 12 m/s, and the speed of light is exactly 299,792,458 m/s.
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.
