Convert Mile per hour to Meter per second
Convert speed from miles per hour (mph) to meters per second (m/s) — the SI unit of speed. This conversion is common in physics, biomechanics, and sports science, where everyday speeds in mph need to be expressed in SI units for calculations and comparisons.

Frequently Asked Questions
How many m/s is 1 mph?
1 mile per hour equals 0.44704 meters per second. The conversion is exact: 1 mile = 1,609.344 m and 1 hour = 3,600 s, so 1 mph = 1,609.344 ÷ 3,600 = 0.44704 m/s.
How do I convert mph to m/s without a calculator?
Multiply by 0.447. For a quick mental estimate, divide by 2.237 — or multiply by 4 and divide by 9. For example, 60 mph × 4 = 240 ÷ 9 ≈ 26.7 m/s (exact: 26.82 m/s).
How many m/s is 60 mph?
60 mph equals 26.82 m/s. This is a typical highway speed in the US. For comparison, 100 km/h equals 27.78 m/s — very close in practical terms.
What is the difference between mph and m/s?
Miles per hour (mph) is used for everyday transportation speeds in the US and UK. Meters per second (m/s) is the SI unit of speed, used in science and engineering. 1 m/s = 2.237 mph, so m/s values are always much smaller than the corresponding mph values.
