## 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 21.2 feet per second into knots we have to multiply 21.2 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

21.2 ft/s → V(kt)

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

V(kt) = 21.2 ft/s × 0.59248380129641 kt

V(kt) = 12.560656587484 kt

The final result is:

21.2 ft/s → 12.560656587484 kt

We conclude that 21.2 feet per second is equivalent to 12.560656587484 knots:

21.2 feet per second = 12.560656587484 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.079613672504705 × 21.2 feet per second.

Another way is saying that 21.2 feet per second is equal to 1 ÷ 0.079613672504705 knots.

## Approximate result

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

21.2 ft/s ≅ 12.561 kt

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