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 815 feet per second into knots we have to multiply 815 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

815 ft/s → V_(kt)

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

V_(kt) = 815 ft/s × 0.59248380129641 kt

V_(kt) = 482.87429805657 kt

The final result is:

815 ft/s → 482.87429805657 kt

We conclude that 815 feet per second is equivalent to 482.87429805657 knots:

815 feet per second = 482.87429805657 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0020709323399997 × 815 feet per second.

Another way is saying that 815 feet per second is equal to 1 ÷ 0.0020709323399997 knots.

Approximate result

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

815 ft/s ≅ 482.874 kt

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