## 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 1109 feet per second into kilometers per hour we have to multiply 1109 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

1109 ft/s → V(km/h)

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

V(km/h) = 1109 ft/s × 1.0972799999991 km/h

V(km/h) = 1216.883519999 km/h

The final result is:

1109 ft/s → 1216.883519999 km/h

We conclude that 1109 feet per second is equivalent to 1216.883519999 kilometers per hour:
