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 921 feet per second into kilometers per hour we have to multiply 921 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

921 ft/s → V_(km/h)

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

V_(km/h) = 921 ft/s × 1.0972799999991 km/h

V_(km/h) = 1010.5948799992 km/h

The final result is:

921 ft/s → 1010.5948799992 km/h

We conclude that 921 feet per second is equivalent to 1010.5948799992 kilometers per hour:

921 feet per second = 1010.5948799992 kilometers per hour
