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 423 miles per hour into meters per second we have to multiply 423 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

423 mph → V_(m/s)

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

V_(m/s) = 423 mph × 0.44704 m/s

V_(m/s) = 189.09792 m/s

The final result is:

423 mph → 189.09792 m/s

We conclude that 423 miles per hour is equivalent to 189.09792 meters per second:

423 miles per hour = 189.09792 meters per second
