## 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 511 feet per second into kilometers per hour we have to multiply 511 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

511 ft/s → V(km/h)

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

V(km/h) = 511 ft/s × 1.0972799999991 km/h

V(km/h) = 560.71007999955 km/h

The final result is:

511 ft/s → 560.71007999955 km/h

We conclude that 511 feet per second is equivalent to 560.71007999955 kilometers per hour:

511 feet per second = 560.71007999955 kilometers per hour
