231 ft/s → V(km/h)

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

V(km/h) = 231 ft/s × 1.0972799999991 km/h

V(km/h) = 253.4716799998 km/h

The final result is:

231 ft/s → 253.4716799998 km/h

We conclude that 231 feet per second is equivalent to 253.4716799998 kilometers per hour:
