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 1085 feet per second into knots we have to multiply 1085 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

1085 ft/s → V_(kt)

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

V_(kt) = 1085 ft/s × 0.59248380129641 kt

V_(kt) = 642.8449244066 kt

The final result is:

1085 ft/s → 642.8449244066 kt

We conclude that 1085 feet per second is equivalent to 642.8449244066 knots:

1085 feet per second = 642.8449244066 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0015555851217509 × 1085 feet per second.

Another way is saying that 1085 feet per second is equal to 1 ÷ 0.0015555851217509 knots.

Approximate result

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

1085 ft/s ≅ 642.845 kt

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