## 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 31 feet per second into knots we have to multiply 31 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

31 ft/s → V(kt)

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

V(kt) = 31 ft/s × 0.59248380129641 kt

V(kt) = 18.366997840189 kt

The final result is:

31 ft/s → 18.366997840189 kt

We conclude that 31 feet per second is equivalent to 18.366997840189 knots:

31 feet per second = 18.366997840189 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.054445479261282 × 31 feet per second.

Another way is saying that 31 feet per second is equal to 1 ÷ 0.054445479261282 knots.

## Approximate result

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

31 ft/s ≅ 18.367 kt

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