## 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 747 feet per second into kilometers per hour we have to multiply 747 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

747 ft/s → V(km/h)

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

V(km/h) = 747 ft/s × 1.0972799999991 km/h

V(km/h) = 819.66815999934 km/h

The final result is:

747 ft/s → 819.66815999934 km/h

We conclude that 747 feet per second is equivalent to 819.66815999934 kilometers per hour:
