About Converting Maches to ft/s
Mach and ft/s both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Mach at standard sea-level conditions, and feet per second.
Formula
ft/s = maches × 1116.43700787
This factor comes from each unit's defined relationship to the category's base unit: 1 mach equals 340.29 base units, and 1 ft/s equals 0.3048 base units, so dividing one by the other gives the direct mach-to-ft/s factor of 1116.43700787.
Simple example
1 Ma × 1116.437008 = 1,116.437008 ft/s
1 mach = 1,116.437008 ft/s.
Real-world example
10 Ma × 1116.437008 = 11,164.37008 ft/s
10 maches = 11,164.37008 ft/s.
