## 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 431 feet per second into kilometers per hour we have to multiply 431 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

431 ft/s → V(km/h)

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

V(km/h) = 431 ft/s × 1.0972799999991 km/h

V(km/h) = 472.92767999962 km/h

The final result is:

431 ft/s → 472.92767999962 km/h

We conclude that 431 feet per second is equivalent to 472.92767999962 kilometers per hour:
