## 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 21.6 feet per second into knots we have to multiply 21.6 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

21.6 ft/s → V(kt)

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

V(kt) = 21.6 ft/s × 0.59248380129641 kt

V(kt) = 12.797650108002 kt

The final result is:

21.6 ft/s → 12.797650108002 kt

We conclude that 21.6 feet per second is equivalent to 12.797650108002 knots:

21.6 feet per second = 12.797650108002 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.078139345236099 × 21.6 feet per second.

Another way is saying that 21.6 feet per second is equal to 1 ÷ 0.078139345236099 knots.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point six feet per second is approximately twelve point seven nine eight knots:

21.6 ft/s ≅ 12.798 kt

An alternative is also that one knot is approximately zero point zero seven eight times twenty-one point six feet per second.
