9 ft/s → V(km/h)

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

V(km/h) = 9 ft/s × 1.0972799999991 km/h

V(km/h) = 9.8755199999921 km/h

The final result is:

9 ft/s → 9.8755199999921 km/h

We conclude that 9 feet per second is equivalent to 9.8755199999921 kilometers per hour:
