Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 809 knots into feet per second we have to multiply 809 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

809 kt → V_(ft/s)

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

V_(ft/s) = 809 kt × 1.6878098570997 ft/s

V_(ft/s) = 1365.4381743937 ft/s

The final result is:

809 kt → 1365.4381743937 ft/s

We conclude that 809 knots is equivalent to 1365.4381743937 feet per second:

809 knots = 1365.4381743937 feet per second

Alternative conversion
