Conversion formula

The conversion factor from feet per second to kilometers per hour is 1.0972799999991, which means that 1 foot per second is equal to 1.0972799999991 kilometers per hour:

1 ft/s = 1.0972799999991 km/h

To convert 424 feet per second into kilometers per hour we have to multiply 424 by the conversion factor in order to get the velocity amount from feet per second to kilometers per hour. We can also form a simple proportion to calculate the result:

1 ft/s → 1.0972799999991 km/h

424 ft/s → V_(km/h)

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

V_(km/h) = 424 ft/s × 1.0972799999991 km/h

V_(km/h) = 465.24671999963 km/h

The final result is:

424 ft/s → 465.24671999963 km/h

We conclude that 424 feet per second is equivalent to 465.24671999963 kilometers per hour:
