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 1643 feet per second into knots we have to multiply 1643 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

1643 ft/s → V_(kt)

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

V_(kt) = 1643 ft/s × 0.59248380129641 kt

V_(kt) = 973.45088553 kt

The final result is:

1643 ft/s → 973.45088553 kt

We conclude that 1643 feet per second is equivalent to 973.45088553 knots:

1643 feet per second = 973.45088553 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0010272731936091 × 1643 feet per second.

Another way is saying that 1643 feet per second is equal to 1 ÷ 0.0010272731936091 knots.

Approximate result

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

1643 ft/s ≅ 973.451 kt

An alternative is also that one knot is approximately zero point zero zero one times one thousand six hundred forty-three feet per second.
