## 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 504 feet per second into kilometers per hour we have to multiply 504 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

504 ft/s → V(km/h)

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

V(km/h) = 504 ft/s × 1.0972799999991 km/h

V(km/h) = 553.02911999956 km/h

The final result is:

504 ft/s → 553.02911999956 km/h

We conclude that 504 feet per second is equivalent to 553.02911999956 kilometers per hour:

504 feet per second = 553.02911999956 kilometers per hour

## Alternative conversion
