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 990 feet per second into knots we have to multiply 990 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

990 ft/s → V_(kt)

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

V_(kt) = 990 ft/s × 0.59248380129641 kt

V_(kt) = 586.55896328344 kt

The final result is:

990 ft/s → 586.55896328344 kt

We conclude that 990 feet per second is equivalent to 586.55896328344 knots:

990 feet per second = 586.55896328344 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0017048584415149 × 990 feet per second.

Another way is saying that 990 feet per second is equal to 1 ÷ 0.0017048584415149 knots.

Approximate result

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

990 ft/s ≅ 586.559 kt

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