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.
The SI measurement of speed and velocity. This is the number of meters travelled in one second of time. The accompanying acceleration unit is meters per second per second (m/s²).
