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 683.7 feet per second into knots we have to multiply 683.7 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

683.7 ft/s → V_(kt)

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

V_(kt) = 683.7 ft/s × 0.59248380129641 kt

V_(kt) = 405.08117494635 kt

The final result is:

683.7 ft/s → 405.08117494635 kt

We conclude that 683.7 feet per second is equivalent to 405.08117494635 knots:

683.7 feet per second = 405.08117494635 knots

Alternative conversion
