FAQ
What is the conversion factor from Mach to ft/s?
1 Mach equals 1116.437 ft/s. To convert, multiply the value in Mach (sea level, 15 °C) by 1116.437.
How do I convert 1 Mach to ft/s?
1 Mach = 1116.44 ft/s. For any value, multiply by 1116.437.
How do I convert ft/s back to Mach?
Divide by the same factor — or equivalently, multiply by 0.0008957066. So 1 ft/s = 0.000895707 Mach.
When would I need to convert Mach (sea level, 15 °C) to foot per second?
Velocity conversions are needed for fluid flow analysis (line velocity targets, erosional limits), gas-stream calculations, and equipment specs that mix m/s, ft/s and engineering speed units.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
