How to convert meters per second to miles per hour
1 meter per second = 2.236936292 miles per hour. To convert meters per second to miles per hour, multiply by 2.236936292. One meter per second is the SI unit of speed, 3.6 km/h. One mile per hour is 1,609.344 m covered in one hour.
Worked examples
- 10 meters per second = 22.3694 mph (10 × 2.2369363)
- 20 meters per second = 44.7387 mph (20 × 2.2369363)
- 50 meters per second = 111.847 mph (50 × 2.2369363)
Where this conversion comes up
Meters per second are used for physics, wind speed in weather models and sprint statistics; miles per hour for speed limits and car speedometers in the US and UK. Multiply by 2.237: 10 m/s is 22.4 mph, hurricane-force wind at 33 m/s is 74 mph, and the speed of sound (343 m/s) is 767 mph.
Quick estimate
Multiply by 2.2 (1.7% low), or double it and add 12%.
Common mistakes
- Dividing instead of multiplying. A mile per hour is smaller than a meter per second, so the number of miles per hour must come out larger: 10 meters per second = 22.3694 mph.
- Rounding too early. Keep the full factor until the last step; rounding 2.24 to 2 first puts large values noticeably off.
