## 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 2121 feet per second into knots we have to multiply 2121 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

2121 ft/s → V(kt)

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

V(kt) = 2121 ft/s × 0.59248380129641 kt

V(kt) = 1256.6581425497 kt

The final result is:

2121 ft/s → 1256.6581425497 kt

We conclude that 2121 feet per second is equivalent to 1256.6581425497 knots:

2121 feet per second = 1256.6581425497 knots
