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 612 feet per second into kilometers per hour we have to multiply 612 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

612 ft/s → V_(km/h)

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

V_(km/h) = 612 ft/s × 1.0972799999991 km/h

V_(km/h) = 671.53535999946 km/h

The final result is:

612 ft/s → 671.53535999946 km/h

We conclude that 612 feet per second is equivalent to 671.53535999946 kilometers per hour:
