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 80 feet per second into knots we have to multiply 80 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

80 ft/s → V(kt)

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

V(kt) = 80 ft/s × 0.59248380129641 kt

V(kt) = 47.398704103713 kt

The final result is:

80 ft/s → 47.398704103713 kt

We conclude that 80 feet per second is equivalent to 47.398704103713 knots:

80 feet per second = 47.398704103713 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.021097623213747 × 80 feet per second.

Another way is saying that 80 feet per second is equal to 1 ÷ 0.021097623213747 knots.

Approximate result

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

80 ft/s ≅ 47.399 kt

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