## 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 25.5 feet per second into kilometers per hour we have to multiply 25.5 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

25.5 ft/s → V(km/h)

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

V(km/h) = 25.5 ft/s × 1.0972799999991 km/h

V(km/h) = 27.980639999978 km/h

The final result is:

25.5 ft/s → 27.980639999978 km/h

We conclude that 25.5 feet per second is equivalent to 27.980639999978 kilometers per hour:

25.5 feet per second = 27.980639999978 kilometers per hour

## Alternative conversion
