- Mach number - Wikipedia
The Mach number (M or Ma), often only Mach, ( mɑːk ; German: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound [1][2] It is named after the Austrian physicist and philosopher Ernst Mach

The Mach number is the ratio of the speed of the aircraft, or the speed of the gas, to the speed of sound in the gas The speed of sound is equal to the speed of transmission of small, isentropic disturbances in the flow

Because of the importance of this speed ratio, aerodynamicists have designated it with a special parameter called the Mach number in honor of Ernst Mach, a late 19th century physicist who studied gas dynamics
