## 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 42.6 feet per second into kilometers per hour we have to multiply 42.6 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

42.6 ft/s → V(km/h)

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

V(km/h) = 42.6 ft/s × 1.0972799999991 km/h

V(km/h) = 46.744127999963 km/h

The final result is:

42.6 ft/s → 46.744127999963 km/h

We conclude that 42.6 feet per second is equivalent to 46.744127999963 kilometers per hour:

42.6 feet per second = 46.744127999963 kilometers per hour

## Alternative conversion
