Formula
Formula
m/s = mph × 0.44704
Multiply any value in miles per hour by 0.44704 to obtain the value in metres per second.
Worked example
Convert 60 mph to m/s.
- 01Start with 60 mph.
- 02Multiply by the conversion factor: 60 × 0.44704 = 26.8224 m/s.
Result60 mph = 26.8224 m/s

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