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 9998 feet per second into kilometers per hour we have to multiply 9998 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

9998 ft/s → V_(km/h)

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

V_(km/h) = 9998 ft/s × 1.0972799999991 km/h

V_(km/h) = 10970.605439991 km/h

The final result is:

9998 ft/s → 10970.605439991 km/h

We conclude that 9998 feet per second is equivalent to 10970.605439991 kilometers per hour:
