About converting Miles per Hour to Meters per Second
Miles per Hour (mph) and Meters per Second (m/s) are both units of speed, so converting between them is a single multiplication: multiply your Miles per Hour figure by 0.447. Ten Miles per Hour comes to 4.4704 Meters per Second, and a hundred works out at 44.704 Meters per Second.
Rule of thumb: going from Miles per Hour to Meters per Second divides, so the figure always shrinks — it takes about 2.2369 Miles per Hour to make a single Meter per Second. If your answer came out bigger, you have the conversion the wrong way round.
What is a Mile per Hour?
Miles per hour is the road-speed unit that refused to die. It is posted on the signs and printed on the speedometers of the United States and the United Kingdom, two countries that otherwise use metric for most scientific and industrial work — a split that leaves British drivers buying fuel in litres while measuring their speed in miles. It has a second life in the media of both countries, where wind gusts, pitch speeds and tennis serves are quoted in mph out of pure habit rather than for any technical reason.
What is a Meter per Second?
The meter per second is the SI unit of speed and the one physics actually runs on — every equation involving velocity, momentum or acceleration expects it, and acceleration itself is measured in meters per second, per second. Yet almost nobody quotes a journey in it. Drivers reach for km/h or mph, sailors and pilots for knots, and the coherent unit stays in the lab. Where it does surface publicly is in scientific wind-speed data, in sprint analysis, and generally in anything measured by instrument rather than read off a dashboard.
To put both in perspective: a US interstate limit is typically 65 to 75 miles per hour, while a brisk walking pace is about 1.4 meters per second.

Is this Miles per Hour to Meters per Second conversion exact?
The definition is exact — Miles per Hour and Meters per Second are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
