Formula
Formula
mph = m/s × 2.236936
Multiply any value in metres per second by 2.236936 to obtain the value in miles per hour.
Worked example
Convert 10 m/s to mph.
- 01Start with 10 m/s.
- 02Multiply by the conversion factor: 10 × 2.236936 = 22.3694 mph.
Result10 m/s = 22.3694 mph

FAQ
What is the conversion factor from m/s to mph?
1 m/s equals 2.236936 mph. To convert, multiply the value in metres per second by 2.236936.
How do I convert 1 m/s to mph?
1 m/s = 2.23694 mph. For any value, multiply by 2.236936.
How do I convert mph back to m/s?
Divide by the same factor — or equivalently, multiply by 0.44704. So 1 mph = 0.44704 m/s.
When would I need to convert metre per second to mile per hour?
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).
