Rendered to 6 significant figures.
Formula
Formula
ft/min = mm/s × 0.1968504
Multiply any value in millimetres per second by 0.1968504 to obtain the value in feet per minute.
Worked example
Convert 10 mm/s to ft/min.
- 01Start with 10 mm/s.
- 02Multiply by the conversion factor: 10 × 0.1968504 = 1.9685 ft/min.
Result10 mm/s = 1.9685 ft/min

FAQ
What is the conversion factor from mm/s to ft/min?
1 mm/s equals 0.1968504 ft/min. To convert, multiply the value in millimetres per second by 0.1968504.
How do I convert 1 mm/s to ft/min?
1 mm/s = 0.19685 ft/min. For any value, multiply by 0.1968504.
How do I convert ft/min back to mm/s?
Divide by the same factor — or equivalently, multiply by 5.08. So 1 ft/min = 5.08 mm/s.
When would I need to convert millimetre per second to foot per minute?
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).
