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 815 knots into feet per second we have to multiply 815 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

815 kt → V_(ft/s)

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

V_(ft/s) = 815 kt × 1.6878098570997 ft/s

V_(ft/s) = 1375.5650335363 ft/s

The final result is:

815 kt → 1375.5650335363 ft/s

We conclude that 815 knots is equivalent to 1375.5650335363 feet per second:

815 knots = 1375.5650335363 feet per second

Alternative conversion
