Miles Per Hour to Meters Per Second (mph to m/s) and Meters Per Second to Miles Per Hour (m/s to mph) Conversion
Feel free to convert miles per hour to meters per second (mph to m/s) and meters per second to miles per hour (m/s to mph) using our conversion chart and conversion calculator, and learn the relationship between these two units.
Conversion of miles per hour to meters per second (mph to m/s) and meters per second to miles per hour (m/s to mph) is an easy one since both units are used for measuring speed. While the meter is a unit of the SI system of units, obviously, the mile is not a unit of the SI system of units, but it is still used very often (obviously).

Conversion of miles per hour to meters per second (mph to m/s) and meters per second to miles per hour (m/s to mph) is an easy one since both units are used for measuring speed.

Meters and miles are used to measure length, while seconds and hours are used to measure time.
Their relationships are as follows:
1 mile = 1609.344 m → 1 meter = 1/1609.344 mile
1 hour = 3600 seconds → 1 second = 1/3600 hour
Note: there is also a nautical mile (nm) which is 1852 meters, but the speed given in nautical miles per hour are knots and not mph. This article is about speed given in miles per hour (mph).
Thus, if we want to convert mph to m/s and m/s to mph, we can write:
1 mph = 1609.344 m / 3600 s = 0.44704 m/s
1 m/s = (1/1609.344) miles / (1/3600) hour = 3600 miles / 1609.344 hour= ~2.23693629 mph
These last two formulas allow us to convert m/s to mph and mph to m/s easily.
Miles Per Hour to Meters Per Second (mph to m/s) and Meters Per Second to Miles Per Hour (m/s to mph) Conversion Examples
How many mph is 4 m/s?
In order to convert the speed given in meters per second to the speed in miles per hour, we can write:
v = 4 m/s = 4 * 2.2369 mph = ~8.9476 mph
So, 4 m/s is equal to 8.9476 mph.
How many m/s is 16 mph?
In order to convert the speed given in mph to the speed given in meters per second, we can write
v = 16 mph = 16 * 0.44704 = 7.15264 m/s
So, 16 mph is equal to 7.15264 m/s.
