## 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 505 feet per second into kilometers per hour we have to multiply 505 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

505 ft/s → V(km/h)

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

V(km/h) = 505 ft/s × 1.0972799999991 km/h

V(km/h) = 554.12639999956 km/h

The final result is:

505 ft/s → 554.12639999956 km/h

We conclude that 505 feet per second is equivalent to 554.12639999956 kilometers per hour:

505 feet per second = 554.12639999956 kilometers per hour
