Miles per Hour to Meters per Second Converter (mph to m/s)
1 mph = 0.44704 m/s exactly. Convert miles per hour to meters per second for physics problems, tornado ratings and pitch speeds, with mph and m/s charts.
Meter per Second (m/s) = Mile per Hour (mph) × 0.44704
Mile per Hour (mph): Miles per hour is the road-speed unit used in the United States and the United Kingdom. The international mile is exactly 1609.344 m, so 1 mph is exactly 0.44704 m/s or 1.609344 km/h.
Meter per Second (m/s): The metre per second is the SI unit of speed: an object at 1 m/s covers one metre every second. It is used in physics and engineering and for wind speeds in weather forecasts.
| Mile per Hour (mph) | Meter per Second (m/s) |
|---|---|
| 1 | 0.44704 |
| 5 | 2.2352 |
| 10 | 4.4704 |
| 25 | 11.176 |
| 50 | 22.352 |
| 100 | 44.704 |
Physics, engineering and sports science calculate in meters per second, but American data on cars, wind, storms and ball speeds come in miles per hour. Because the mile is exactly 1,609.344 m and the hour 3,600 s, 1 mph is exactly 0.44704 m/s, so the conversion has no rounding built into it.
Tornado ratings are a good example. The National Weather Service rates tornadoes on the Enhanced Fujita scale from the damage they leave, with wind estimates in mph for 3-second gusts; an EF5 means gusts over 200 mph, about 89 m/s. Baseball analysts make the same conversion to work out how long a pitch takes to reach the plate.

Formula
Meter per Second (m/s) = Mile per Hour (mph) × 0.44704
Mile per Hour (mph) = Meter per Second (m/s) × 2.23693629205
Both factors come from exact definitions: 1 meter per second = 2.23693629205 miles per hour and 1 mile per hour = 0.44704 meters per second (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
60 mph × 0.44704 = 26.8224 m/s
20 m/s × 2.23693629205 ≈ 44.7387 mph

Quick mental estimate
Multiply by 9 and divide by 20: 60 mph → 540 ÷ 20 = 27 m/s, against an exact 26.82 m/s. The shortcut uses 0.45 for 0.44704, so it reads about 0.7% high.
Use the converter or the charts when the exact figure matters.
The two units
Mile per Hour (mph): Miles per hour is the road-speed unit used in the United States and the United Kingdom. The international mile is exactly 1609.344 m, so 1 mph is exactly 0.44704 m/s or 1.609344 km/h.
Meter per Second (m/s): The metre per second is the SI unit of speed: an object at 1 m/s covers one metre every second. It is used in physics and engineering and for wind speeds in weather forecasts.
Frequently asked questions
How long does a 100 mph fastball take to reach home plate?
100 mph is 44.704 m/s. The pitching rubber is 60.5 ft (18.44 m) from home plate and the ball is released a few feet in front of it, so it arrives in roughly 0.4 seconds, a little more because it slows on the way.
How fast is 60 mph in meters per second?
About 26.8 m/s (26.8224 exactly). A car at that speed covers the length of a tennis court, 23.77 m, in under a second.
Why are tornado wind speeds only estimates?
Few tornadoes pass over a working anemometer, so the EF scale infers wind speed from damage to buildings and trees. Each rating is a range of 3-second gust speeds, and the m/s figures here are conversions of those mph estimates.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
