mph to m/s – convert miles per hour to metres per second
Convert mph to m/s (miles per hour to metres per second) for running, cycling, driving and physics problems. This page opens the main speed converter with mph → m/s pre-selected so you can enter any road speed and get metres per second.

Use main converter (mph → m/s) or switch to m/s → mphThe homepage also supports km/h and knots. You can keep the Tool Hub open for a Pomodoro or stopwatch while you train.
Quick reference: mph to m/s
The exact factor is 1 mph ≈ 0.44704 m/s, so: m/s = mph × 0.44704.
| mph | m/s (approx.) |
|---|---|
| 5 mph | 2.24 m/s |
| 10 mph | 4.47 m/s |
| 20 mph | 8.94 m/s |
| 30 mph | 13.41 m/s |
| 60 mph | 26.82 m/s |
| 70 mph | 31.29 m/s |
How to convert mph to m/s
Use either of these equivalent formulas:
m/s = mph × 0.44704
or m/s = mph × 1609.344 ÷ 3,600
Examples:
- 30 mph × 0.44704 ≈ 13.41 m/s
- 50 mph × 0.44704 ≈ 22.35 m/s
- 80 mph × 0.44704 ≈ 35.76 m/s
Why convert miles per hour to metres per second?
- Physics and engineering problems that are written in SI units.
- Comparing running pace or sprint speed to distances covered each second.
- Working with braking distances or stopping times in safety calculations.
- Relating road speeds to acceleration or deceleration in m/s².
