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 681 feet per second into knots we have to multiply 681 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

681 ft/s → V_(kt)

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

V_(kt) = 681 ft/s × 0.59248380129641 kt

V_(kt) = 403.48146868285 kt

The final result is:

681 ft/s → 403.48146868285 kt

We conclude that 681 feet per second is equivalent to 403.48146868285 knots:

681 feet per second = 403.48146868285 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0024784285713653 × 681 feet per second.

Another way is saying that 681 feet per second is equal to 1 ÷ 0.0024784285713653 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that six hundred eighty-one feet per second is approximately four hundred three point four eight one knots:

681 ft/s ≅ 403.481 kt

An alternative is also that one knot is approximately zero point zero zero two times six hundred eighty-one feet per second.
