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 521 knots into feet per second we have to multiply 521 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

521 kt → V_(ft/s)

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

V_(ft/s) = 521 kt × 1.6878098570997 ft/s

V_(ft/s) = 879.34893554896 ft/s

The final result is:

521 kt → 879.34893554896 ft/s

We conclude that 521 knots is equivalent to 879.34893554896 feet per second:

521 knots = 879.34893554896 feet per second

Alternative conversion
