## Conversion formula

The conversion factor from kilometers per hour to feet per second is 0.91134441528215, which means that 1 kilometer per hour is equal to 0.91134441528215 feet per second:

1 km/h = 0.91134441528215 ft/s

To convert 811 kilometers per hour into feet per second we have to multiply 811 by the conversion factor in order to get the velocity amount from kilometers per hour to feet per second. We can also form a simple proportion to calculate the result:

1 km/h → 0.91134441528215 ft/s

811 km/h → V(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V(ft/s) = 811 km/h × 0.91134441528215 ft/s

V(ft/s) = 739.10032079383 ft/s

The final result is:

811 km/h → 739.10032079383 ft/s

We conclude that 811 kilometers per hour is equivalent to 739.10032079383 feet per second:

811 kilometers per hour = 739.10032079383 feet per second

## Alternative conversion
