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 840 miles per hour into meters per second we have to multiply 840 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

840 mph → V_(m/s)

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

V_(m/s) = 840 mph × 0.44704 m/s

V_(m/s) = 375.5136 m/s

The final result is:

840 mph → 375.5136 m/s

We conclude that 840 miles per hour is equivalent to 375.5136 meters per second:

840 miles per hour = 375.5136 meters per second
