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 515.7 knots into feet per second we have to multiply 515.7 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

515.7 kt → V_(ft/s)

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

V_(ft/s) = 515.7 kt × 1.6878098570997 ft/s

V_(ft/s) = 870.40354330633 ft/s

The final result is:

515.7 kt → 870.40354330633 ft/s

We conclude that 515.7 knots is equivalent to 870.40354330633 feet per second:

515.7 knots = 870.40354330633 feet per second
