Mach is a speed measurement based on the speed of sound. Since sound travels at different speeds in different conditions, the calculations here are given for 20°C in dry air at sea level. Mach is typically used in aviation and space exploration.
This is a measurement of speed typically used in countries using the metric system for transport. Road speed limits are given in kilometers per hour which is abbreviated as kph or km/h.
