## 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 613 feet per second into kilometers per hour we have to multiply 613 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

613 ft/s → V(km/h)

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

V(km/h) = 613 ft/s × 1.0972799999991 km/h

V(km/h) = 672.63263999946 km/h

The final result is:

613 ft/s → 672.63263999946 km/h

We conclude that 613 feet per second is equivalent to 672.63263999946 kilometers per hour:
