## 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 31.8 feet per second into kilometers per hour we have to multiply 31.8 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

31.8 ft/s → V(km/h)

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

V(km/h) = 31.8 ft/s × 1.0972799999991 km/h

V(km/h) = 34.893503999972 km/h

The final result is:

31.8 ft/s → 34.893503999972 km/h

We conclude that 31.8 feet per second is equivalent to 34.893503999972 kilometers per hour:

31.8 feet per second = 34.893503999972 kilometers per hour
