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 345 feet per second into kilometers per hour we have to multiply 345 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

345 ft/s → V_(km/h)

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

V_(km/h) = 345 ft/s × 1.0972799999991 km/h

V_(km/h) = 378.5615999997 km/h

The final result is:

345 ft/s → 378.5615999997 km/h

We conclude that 345 feet per second is equivalent to 378.5615999997 kilometers per hour:
