About Mach (at sea level)

Mach number represents the ratio of an object's speed to the speed of sound. Mach 1 equals approximately 1,235 km/h at sea level.

Common uses: aviation, aerospace, military.

About Foot/Second

The foot/second (ft/s) is a unit of speed and velocity. One foot/second equals 0.3048 metre per seconds. UnitConvertLab converts it against every other speed unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: speed calculations, engineering and science, education.
