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 5621 feet per second into knots we have to multiply 5621 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

5621 ft/s → V_(kt)

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

V_(kt) = 5621 ft/s × 0.59248380129641 kt

V_(kt) = 3330.3514470871 kt

The final result is:

5621 ft/s → 3330.3514470871 kt

We conclude that 5621 feet per second is equivalent to 3330.3514470871 knots:

5621 feet per second = 3330.3514470871 knots

Alternative conversion
