## Conversion formula

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 4.2 meters per second into miles per hour we have to multiply 4.2 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

4.2 m/s → V(mph)

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

V(mph) = 4.2 m/s × 2.2369362920544 mph

V(mph) = 9.3951324266285 mph

The final result is:

4.2 m/s → 9.3951324266285 mph

We conclude that 4.2 meters per second is equivalent to 9.3951324266285 miles per hour:

4.2 meters per second = 9.3951324266285 miles per hour
