Unit converter
Metres per second to miles per hour.
Convert m/s to mph and mph to m/s. Type in either box and the other follows. Physics works in metres per second; speed limits do not. One metre per second is 2.24 mph.
| m/s | mph |
|---|---|
| 1 m/s | 2.23694 mph |
| 2 m/s | 4.47387 mph |
| 3 m/s | 6.71081 mph |
| 5 m/s | 11.1847 mph |
| 10 m/s | 22.3694 mph |
| 15 m/s | 33.554 mph |
| 20 m/s | 44.7387 mph |
| 25 m/s | 55.9234 mph |
| 30 m/s | 67.1081 mph |
| 50 m/s | 111.847 mph |
- Conversion goes through m/s in both directions, so neither figure is rounded on the way.
Definitions
- The metre per second is the SI unit of speed, and the one physics equations expect.
- The mile per hour is the speed limit unit in the UK and the US. Exactly 0.447 04 m/s.
- This conversion is exact by definition. 1 m/s = 2.236936292 mph.
- Speed is converted through m/s.
How it works
One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.
The value passes through m/s, the unit every other speed unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general speed converter always agree.
Display precision sets a maximum number of significant figures and trims trailing zeroes, so it changes what you see and never what was calculated. The editable box always holds a plain number at full working precision, so you can carry on from either side.
Common questions this answers: how many miles per hour in a metre per second (2.23694), how many metres per second in a mile per hour (0.44704), and what 10 m/s is in miles per hour (22.3694 mph).
