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 858 feet per second into knots we have to multiply 858 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

858 ft/s → V_(kt)

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

V_(kt) = 858 ft/s × 0.59248380129641 kt

V_(kt) = 508.35110151232 kt

The final result is:

858 ft/s → 508.35110151232 kt

We conclude that 858 feet per second is equivalent to 508.35110151232 knots:

858 feet per second = 508.35110151232 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0019671443555941 × 858 feet per second.

Another way is saying that 858 feet per second is equal to 1 ÷ 0.0019671443555941 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that eight hundred fifty-eight feet per second is approximately five hundred eight point three five one knots:

858 ft/s ≅ 508.351 kt

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