About these units
Mach Number (M)
Mach number is speed divided by the local speed of sound; this converter uses 343 m/s, the value in air at 20 °C. Mach 1 at sea level is therefore about 1,235 km/h.
Meters per Second (m/s)
Meters per second is the SI unit of speed. Walking pace is about 1.4 m/s, and 1 m/s equals 3.6 km/h.
