## 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 111 feet per second into kilometers per hour we have to multiply 111 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

111 ft/s → V(km/h)

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

V(km/h) = 111 ft/s × 1.0972799999991 km/h

V(km/h) = 121.7980799999 km/h

The final result is:

111 ft/s → 121.7980799999 km/h

We conclude that 111 feet per second is equivalent to 121.7980799999 kilometers per hour:

111 feet per second = 121.7980799999 kilometers per hour
