## 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 30 feet per second into knots we have to multiply 30 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

30 ft/s → V(kt)

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

V(kt) = 30 ft/s × 0.59248380129641 kt

V(kt) = 17.774514038892 kt

The final result is:

30 ft/s → 17.774514038892 kt

We conclude that 30 feet per second is equivalent to 17.774514038892 knots:

30 feet per second = 17.774514038892 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.056260328569991 × 30 feet per second.

Another way is saying that 30 feet per second is equal to 1 ÷ 0.056260328569991 knots.

## Approximate result

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

30 ft/s ≅ 17.775 kt

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