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 1680 feet per second into kilometers per hour we have to multiply 1680 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

1680 ft/s → V_(km/h)

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

V_(km/h) = 1680 ft/s × 1.0972799999991 km/h

V_(km/h) = 1843.4303999985 km/h

The final result is:

1680 ft/s → 1843.4303999985 km/h
