## 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 497 feet per second into kilometers per hour we have to multiply 497 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

497 ft/s → V(km/h)

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

V(km/h) = 497 ft/s × 1.0972799999991 km/h

V(km/h) = 545.34815999956 km/h

The final result is:

497 ft/s → 545.34815999956 km/h

We conclude that 497 feet per second is equivalent to 545.34815999956 kilometers per hour:
