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 7139 feet per second into knots we have to multiply 7139 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

7139 ft/s → V_(kt)

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

V_(kt) = 7139 ft/s × 0.59248380129641 kt

V_(kt) = 4229.7418574551 kt

The final result is:

7139 ft/s → 4229.7418574551 kt

We conclude that 7139 feet per second is equivalent to 4229.7418574551 knots:

7139 feet per second = 4229.7418574551 knots
