## 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 315 feet per second into kilometers per hour we have to multiply 315 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

315 ft/s → V(km/h)

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

V(km/h) = 315 ft/s × 1.0972799999991 km/h

V(km/h) = 345.64319999972 km/h

The final result is:

315 ft/s → 345.64319999972 km/h

We conclude that 315 feet per second is equivalent to 345.64319999972 kilometers per hour:

315 feet per second = 345.64319999972 kilometers per hour
