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 2821 feet per second into knots we have to multiply 2821 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

2821 ft/s → V_(kt)

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

V_(kt) = 2821 ft/s × 0.59248380129641 kt

V_(kt) = 1671.3968034572 kt

The final result is:

2821 ft/s → 1671.3968034572 kt

We conclude that 2821 feet per second is equivalent to 1671.3968034572 knots:

2821 feet per second = 1671.3968034572 knots

Alternative conversion
