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 1081 feet per second into knots we have to multiply 1081 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

1081 ft/s → V_(kt)

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

V_(kt) = 1081 ft/s × 0.59248380129641 kt

V_(kt) = 640.47498920142 kt

The final result is:

1081 ft/s → 640.47498920142 kt

We conclude that 1081 feet per second is equivalent to 640.47498920142 knots:

1081 feet per second = 640.47498920142 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0015613412184086 × 1081 feet per second.

Another way is saying that 1081 feet per second is equal to 1 ÷ 0.0015613412184086 knots.

Approximate result

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

1081 ft/s ≅ 640.475 kt

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