## 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 399 feet per second into knots we have to multiply 399 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

399 ft/s → V_{(kt)}

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

V_{(kt)} = 399 ft/s × 0.59248380129641 kt

V_{(kt)} = 236.40103671727 kt

The final result is:

399 ft/s → 236.40103671727 kt

We conclude that **399 feet per second is equivalent to 236.40103671727 knots**:

399 feet per second = 236.40103671727 knots

## Alternative conversion
