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 7221 feet per second into knots we have to multiply 7221 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

7221 ft/s → V_(kt)

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

V_(kt) = 7221 ft/s × 0.59248380129641 kt

V_(kt) = 4278.3255291614 kt

The final result is:

7221 ft/s → 4278.3255291614 kt

We conclude that 7221 feet per second is equivalent to 4278.3255291614 knots:

7221 feet per second = 4278.3255291614 knots
