## 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 13.5 feet per second into knots we have to multiply 13.5 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

13.5 ft/s → V(kt)

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

V(kt) = 13.5 ft/s × 0.59248380129641 kt

V(kt) = 7.9985313175015 kt

The final result is:

13.5 ft/s → 7.9985313175015 kt

We conclude that 13.5 feet per second is equivalent to 7.9985313175015 knots:

13.5 feet per second = 7.9985313175015 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.12502295237776 × 13.5 feet per second.

Another way is saying that 13.5 feet per second is equal to 1 ÷ 0.12502295237776 knots.

## Approximate result

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

13.5 ft/s ≅ 7.999 kt

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