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 3980 feet per second into knots we have to multiply 3980 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

3980 ft/s → V_(kt)

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

V_(kt) = 3980 ft/s × 0.59248380129641 kt

V_(kt) = 2358.0855291597 kt

The final result is:

3980 ft/s → 2358.0855291597 kt

We conclude that 3980 feet per second is equivalent to 2358.0855291597 knots:

3980 feet per second = 2358.0855291597 knots

Alternative conversion
