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 1686 feet per second into knots we have to multiply 1686 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

1686 ft/s → V_(kt)

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

V_(kt) = 1686 ft/s × 0.59248380129641 kt

V_(kt) = 998.92768898574 kt

The final result is:

1686 ft/s → 998.92768898574 kt

We conclude that 1686 feet per second is equivalent to 998.92768898574 knots:

1686 feet per second = 998.92768898574 knots
