How to Convert Meter per Second (Speed) to Mile per Hour
- 1 m/s = 2.236936292 mph
- 1 mph = 0.44704 m/s
- Example: convert 15 m/s to mph: 15 m/s = 15 × 2.236936292 mph = 33.55404438 mph
Formula
mph = m/s × 2.236936292054
Derivation from SI units:
- The SI unit of speed: one metre travelled per second.
- 1 mph = 1609.344 m ÷ 3600 s = 0.44704 m/s exactly.
Both units are defined exactly, so the factor is exact. Meter per Second (Speed) definition: meter per second; Mile per Hour definition: mile per hour.
Worked examples
- A reading of 10 m/s converts to 22.36936292 mph.
10 m/s × 2.236936292 = 22.36936292 mph - A value of 30 m/s is 67.10808876 mph.
30 m/s × 2.236936292 = 67.10808876 mph
