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 857 feet per second into knots we have to multiply 857 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

857 ft/s → V_(kt)

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

V_(kt) = 857 ft/s × 0.59248380129641 kt

V_(kt) = 507.75861771102 kt

The final result is:

857 ft/s → 507.75861771102 kt

We conclude that 857 feet per second is equivalent to 507.75861771102 knots:

857 feet per second = 507.75861771102 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0019694397399063 × 857 feet per second.

Another way is saying that 857 feet per second is equal to 1 ÷ 0.0019694397399063 knots.

Approximate result

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

857 ft/s ≅ 507.759 kt

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