About the units
Mach (Mach)
The speed of sound. This converter uses 340.29 m/s, its value in dry air at 15 °C at sea level; the real figure changes with temperature.
Kilometer per hour (km/h)
The road speed unit in most of the world.
Speed is distance travelled per unit of time. The SI unit is the meter per second. Road speeds use km/h or mph, and a knot is one nautical mile per hour.
