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 3921 feet per second into knots we have to multiply 3921 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

3921 ft/s → V_(kt)

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

V_(kt) = 3921 ft/s × 0.59248380129641 kt

V_(kt) = 2323.1289848832 kt

The final result is:

3921 ft/s → 2323.1289848832 kt

We conclude that 3921 feet per second is equivalent to 2323.1289848832 knots:

3921 feet per second = 2323.1289848832 knots

Alternative conversion
