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 610 feet per second into kilometers per hour we have to multiply 610 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

610 ft/s → V_(km/h)

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

V_(km/h) = 610 ft/s × 1.0972799999991 km/h

V_(km/h) = 669.34079999946 km/h

The final result is:

610 ft/s → 669.34079999946 km/h

We conclude that 610 feet per second is equivalent to 669.34079999946 kilometers per hour:

610 feet per second = 669.34079999946 kilometers per hour
