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 815.1 kilometers per hour into feet per second we have to multiply 815.1 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

815.1 km/h → V_(ft/s)

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

V_(ft/s) = 815.1 km/h × 0.91134441528215 ft/s

V_(ft/s) = 742.83683289648 ft/s

The final result is:

815.1 km/h → 742.83683289648 ft/s

We conclude that 815.1 kilometers per hour is equivalent to 742.83683289648 feet per second:

815.1 kilometers per hour = 742.83683289648 feet per second
