Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 521.7 feet per second into knots we have to multiply 521.7 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

521.7 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 521.7 ft/s × 0.59248380129641 kt

V_(kt) = 309.09879913634 kt

The final result is:

521.7 ft/s → 309.09879913634 kt

We conclude that 521.7 feet per second is equivalent to 309.09879913634 knots:

521.7 feet per second = 309.09879913634 knots

Alternative conversion
