About mph to m/s
Convert mph to m/s instantly, with a reference table of common values. The factor is exact: 1 mph = 0.44704 m/s.
Needed when an imperial speed has to enter a scientific calculation, since physics formulas require metres per second rather than any road unit.
Miles per hour pairs the statute mile with the hour. It survives in the two major English-speaking countries that kept the mile for road distances. It is the road speed unit of the United States and the United Kingdom, and is used for wind speed in American weather reporting. A typical US highway limit is 65 to 70 mph, and a UK motorway limit is 70 mph.
Worked through with real numbers: 10 mph is 4.47 m/s, 50 mph is 22.352 m/s, 100 mph is 44.704 m/s.
As for the other side of the conversion: sound travels at about 343 m/s in air, and light at 299,792,458 m/s exactly.
Every speed unit is a distance divided by a time, so converting between them means converting the distance and the time together. That is why the factors are less memorable than simple length conversions.

Frequently asked questions
How do I convert mph to m/s?
Multiply your mph figure by 0.44704 to get m/s โ or type a value above and read the answer straight off.
How many m/s are in one mph?
1 mph = 0.44704 m/s.
When would I need to convert mph to m/s?
Needed when an imperial speed has to enter a scientific calculation, since physics formulas require metres per second rather than any road unit.
What is a mph, exactly?
Miles per hour pairs the statute mile with the hour. It survives in the two major English-speaking countries that kept the mile for road distances. A typical US highway limit is 65 to 70 mph, and a UK motorway limit is 70 mph.
Where is the m/ actually used?
It is the standard in physics and engineering, and in scientific meteorology for wind speed. Almost every physics formula involving velocity expects it. Sound travels at about 343 m/s in air, and light at 299,792,458 m/s exactly.
Is there anything tricky about speed conversions?
Every speed unit is a distance divided by a time, so converting between them means converting the distance and the time together. That is why the factors are less memorable than simple length conversions.
Is this converter accurate?
Yes. It uses the exact standard factor of 1 mph = 0.44704 m/s, and the conversion runs in your browser so nothing is uploaded.
