## 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 12.9 feet per second into knots we have to multiply 12.9 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

12.9 ft/s → V(kt)

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

V(kt) = 12.9 ft/s × 0.59248380129641 kt

V(kt) = 7.6430410367237 kt

The final result is:

12.9 ft/s → 7.6430410367237 kt

We conclude that 12.9 feet per second is equivalent to 7.6430410367237 knots:

12.9 feet per second = 7.6430410367237 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.13083797341858 × 12.9 feet per second.

Another way is saying that 12.9 feet per second is equal to 1 ÷ 0.13083797341858 knots.

## Approximate result

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

12.9 ft/s ≅ 7.643 kt

An alternative is also that one knot is approximately zero point one three one times twelve point nine feet per second.
