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 247 feet per second into kilometers per hour we have to multiply 247 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

247 ft/s → V(km/h)

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

V(km/h) = 247 ft/s × 1.0972799999991 km/h

V(km/h) = 271.02815999978 km/h

The final result is:

247 ft/s → 271.02815999978 km/h

We conclude that 247 feet per second is equivalent to 271.02815999978 kilometers per hour:
