Formula

Formula
Mach = ft/min × 1.492844e-5

Multiply any value in feet per minute by 1.492844e-5 to obtain the value in Mach (sea level, 15 °C).

Worked example

Convert 100000 ft/min to Mach.

  1. 01Start with 100000 ft/min.
  2. 02Multiply by the conversion factor: 100000 × 1.492844e-5 = 1.49284 Mach.
Result100000 ft/min = 1.49284 Mach

FAQ

What is the conversion factor from ft/min to Mach?
1 ft/min equals 1.492844e-5 Mach. To convert, multiply the value in feet per minute by 1.492844e-5.
How do I convert 1 ft/min to Mach?
1 ft/min = 1.49284e-5 Mach. For any value, multiply by 1.492844e-5.
How do I convert Mach back to ft/min?
Divide by the same factor — or equivalently, multiply by 66986.22. So 1 Mach = 66986.2 ft/min.
When would I need to convert foot per minute to Mach (sea level, 15 °C)?
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).
