## 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 310 feet per second into kilometers per hour we have to multiply 310 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

310 ft/s → V(km/h)

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

V(km/h) = 310 ft/s × 1.0972799999991 km/h

V(km/h) = 340.15679999973 km/h

The final result is:

310 ft/s → 340.15679999973 km/h

We conclude that 310 feet per second is equivalent to 340.15679999973 kilometers per hour:

310 feet per second = 340.15679999973 kilometers per hour

## Alternative conversion
