The conversion factor from meters per second to miles per hour is 2.2369362920544, which means that 1 meter per second is equal to 2.2369362920544 miles per hour:

1 m/s = 2.2369362920544 mph

To convert 18 meters per second into miles per hour we have to multiply 18 by the conversion factor in order to get the velocity amount from meters per second to miles per hour. We can also form a simple proportion to calculate the result:

1 m/s → 2.2369362920544 mph

18 m/s → V(mph)

Solve the above proportion to obtain the velocity V in miles per hour:

V(mph) = 18 m/s × 2.2369362920544 mph

V(mph) = 40.264853256979 mph

The final result is:

18 m/s → 40.264853256979 mph

We conclude that 18 meters per second is equivalent to 40.264853256979 miles per hour:
