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 1390 miles per hour into meters per second we have to multiply 1390 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

1390 mph → V_(m/s)

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

V_(m/s) = 1390 mph × 0.44704 m/s

V_(m/s) = 621.3856 m/s

The final result is:

1390 mph → 621.3856 m/s

We conclude that 1390 miles per hour is equivalent to 621.3856 meters per second:
