How it’s calculated
One mile per hour is exactly 0.44704 m/s (1 609.344 m in 3 600 s).
1 mph = 0.44704 m/s (exact) · 1 m/s ≈ 2.2369363 mph
m/s = mph × 0.44704
- Multiply the value in miles per hour by 0.44704.
- To go back, divide by 0.44704 (or multiply by 2.236936292).
- 1 mph = 0.44704 m/s · 1 m/s = 2.236936292 mph
Step by step
Find the conversion factor
By definition 1 mph = 0.44704 m/s. Source: NIST SP 811 / Handbook 44; BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).
Multiply by the factor written as a fraction
Put mph in the denominator so it cancels, leaving m/s.
