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 489 feet per second into knots we have to multiply 489 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

489 ft/s → V_(kt)

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

V_(kt) = 489 ft/s × 0.59248380129641 kt

V_(kt) = 289.72457883394 kt

The final result is:

489 ft/s → 289.72457883394 kt

We conclude that 489 feet per second is equivalent to 289.72457883394 knots:

489 feet per second = 289.72457883394 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0034515538999995 × 489 feet per second.

Another way is saying that 489 feet per second is equal to 1 ÷ 0.0034515538999995 knots.

Approximate result

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

489 ft/s ≅ 289.725 kt

An alternative is also that one knot is approximately zero point zero zero three times four hundred eighty-nine feet per second.
