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 3947 feet per second into knots we have to multiply 3947 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

3947 ft/s → V_(kt)

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

V_(kt) = 3947 ft/s × 0.59248380129641 kt

V_(kt) = 2338.5335637169 kt

The final result is:

3947 ft/s → 2338.5335637169 kt

We conclude that 3947 feet per second is equivalent to 2338.5335637169 knots:

3947 feet per second = 2338.5335637169 knots

Alternative conversion
