## 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 66.4 feet per second into knots we have to multiply 66.4 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

66.4 ft/s → V(kt)

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

V(kt) = 66.4 ft/s × 0.59248380129641 kt

V(kt) = 39.340924406082 kt

The final result is:

66.4 ft/s → 39.340924406082 kt

We conclude that 66.4 feet per second is equivalent to 39.340924406082 knots:

66.4 feet per second = 39.340924406082 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.025418823149092 × 66.4 feet per second.

Another way is saying that 66.4 feet per second is equal to 1 ÷ 0.025418823149092 knots.

## Approximate result

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

66.4 ft/s ≅ 39.341 kt

An alternative is also that one knot is approximately zero point zero two five times sixty-six point four feet per second.
