The converter above works in both directions and updates as you type. Below you will find the formula, a worked example and a reference table of common values.

Speed conversions divide by audience. Road speeds move between kilometres and miles per hour and are what a driver or a runner needs. Metres per second is what every equation of motion expects, so it is the form any physics problem has to reach. Knots belong to the sea and the air, where one knot is one nautical mile per hour and a nautical mile is one minute of latitude — a system built around navigation rather than around convenience.

mps to mph formula

mile per hour = meter per second × 2.23693629

To go the other way, use meter per second = mile per hour ÷ 2.23693629.

About these units

Metres per second is the SI speed unit and the one every equation of motion expects. Wind speeds in meteorology are usually reported in it.

Miles per hour remains the road-speed unit in the United States and the United Kingdom, which is why British road signs are in miles while everything else on them is metric.

Meter per second is also written metres per second, meters per second, mps and ms-1. Mile per hour is also written miles per hour and mi/h.

Frequently asked questions

How many miles per hour are in a meter per second? +

There are 2.236936 miles per hour in one meter per second.

What is 10 m/s in mph? +

10 m/s equals 22.3694 mph. Multiply 10 by 2.23693629.

How do I convert mile per hour back to meter per second? +

Use meter per second = mile per hour ÷ 2.23693629. The converter above handles both directions, or see our dedicated mph to mps page.

How accurate is this meter per second to mile per hour conversion? +

The factor used is 2.2369362921, carried at full double precision. Where a unit has an exact legal definition the factor is exact rather than approximate. Rounding is applied only to the displayed result, so the answer is never a calculation done on an already-rounded number.

Is there a quick way to estimate m/s to mph in my head? +

Multiply by 9 and divide by 4. That approximates the true factor of 2.236936 to within 0.584%, which is close enough for a mental estimate.
