## 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 253 feet per second into kilometers per hour we have to multiply 253 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

253 ft/s → V(km/h)

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

V(km/h) = 253 ft/s × 1.0972799999991 km/h

V(km/h) = 277.61183999978 km/h

The final result is:

253 ft/s → 277.61183999978 km/h

We conclude that 253 feet per second is equivalent to 277.61183999978 kilometers per hour:
