Conversion formula

The conversion factor from miles per hour to meters per second is 0.44704, which means that 1 mile per hour is equal to 0.44704 meters per second:

1 mph = 0.44704 m/s

To convert 478 miles per hour into meters per second we have to multiply 478 by the conversion factor in order to get the velocity amount from miles per hour to meters per second. We can also form a simple proportion to calculate the result:

1 mph → 0.44704 m/s

478 mph → V_(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V_(m/s) = 478 mph × 0.44704 m/s

V_(m/s) = 213.68512 m/s

The final result is:

478 mph → 213.68512 m/s

We conclude that 478 miles per hour is equivalent to 213.68512 meters per second:

478 miles per hour = 213.68512 meters per second
