## 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 3.5 feet per second into knots we have to multiply 3.5 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

3.5 ft/s → V(kt)

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

V(kt) = 3.5 ft/s × 0.59248380129641 kt

V(kt) = 2.0736933045374 kt

The final result is:

3.5 ft/s → 2.0736933045374 kt

We conclude that 3.5 feet per second is equivalent to 2.0736933045374 knots:

3.5 feet per second = 2.0736933045374 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.48223138774278 × 3.5 feet per second.

Another way is saying that 3.5 feet per second is equal to 1 ÷ 0.48223138774278 knots.

## Approximate result

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

3.5 ft/s ≅ 2.074 kt

An alternative is also that one knot is approximately zero point four eight two times three point five feet per second.
