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 641 feet per second into knots we have to multiply 641 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

641 ft/s → V_(kt)

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

V_(kt) = 641 ft/s × 0.59248380129641 kt

V_(kt) = 379.782116631 kt

The final result is:

641 ft/s → 379.782116631 kt

We conclude that 641 feet per second is equivalent to 379.782116631 knots:

641 feet per second = 379.782116631 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0026330887006236 × 641 feet per second.

Another way is saying that 641 feet per second is equal to 1 ÷ 0.0026330887006236 knots.

Approximate result

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

641 ft/s ≅ 379.782 kt

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