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 1687 feet per second into knots we have to multiply 1687 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

1687 ft/s → V_(kt)

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

V_(kt) = 1687 ft/s × 0.59248380129641 kt

V_(kt) = 999.52017278704 kt

The final result is:

1687 ft/s → 999.52017278704 kt

We conclude that 1687 feet per second is equivalent to 999.52017278704 knots:

1687 feet per second = 999.52017278704 knots

Alternative conversion
