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 28.7 feet per second into knots we have to multiply 28.7 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

28.7 ft/s → V_(kt)

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

V_(kt) = 28.7 ft/s × 0.59248380129641 kt

V_(kt) = 17.004285097207 kt

The final result is:

28.7 ft/s → 17.004285097207 kt

We conclude that 28.7 feet per second is equivalent to 17.004285097207 knots:

28.7 feet per second = 17.004285097207 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.058808705822291 × 28.7 feet per second.

Another way is saying that 28.7 feet per second is equal to 1 ÷ 0.058808705822291 knots.

Approximate result

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

28.7 ft/s ≅ 17.004 kt

An alternative is also that one knot is approximately zero point zero five nine times twenty-eight point seven feet per second.
