What does Mach (20°C, 1 atm) measure?

Mach (20°C, 1 atm) is a ratio comparing an object's speed to the speed of sound in dry air at 20°C and 1 atmospheric pressure.

Why convert Mach to foot per hour?

Converting Mach to foot per hour helps express very high-speed phenomena into an extremely slow unit useful for comparison or precise industrial measurements.

Is the conversion accurate for all conditions?

No, the Mach number is based on standard conditions and actual speeds can vary due to changes in temperature and pressure.
