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 8121 feet per second into knots we have to multiply 8121 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

8121 ft/s → V_(kt)

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

V_(kt) = 8121 ft/s × 0.59248380129641 kt

V_(kt) = 4811.5609503281 kt

The final result is:

8121 ft/s → 4811.5609503281 kt

We conclude that 8121 feet per second is equivalent to 4811.5609503281 knots:

8121 feet per second = 4811.5609503281 knots

Alternative conversion
