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 8221 feet per second into knots we have to multiply 8221 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

8221 ft/s → V_(kt)

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

V_(kt) = 8221 ft/s × 0.59248380129641 kt

V_(kt) = 4870.8093304578 kt

The final result is:

8221 ft/s → 4870.8093304578 kt

We conclude that 8221 feet per second is equivalent to 4870.8093304578 knots:

8221 feet per second = 4870.8093304578 knots

Alternative conversion
