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 1639 feet per second into knots we have to multiply 1639 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

1639 ft/s → V_(kt)

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

V_(kt) = 1639 ft/s × 0.59248380129641 kt

V_(kt) = 971.08095032481 kt

The final result is:

1639 ft/s → 971.08095032481 kt

We conclude that 1639 feet per second is equivalent to 971.08095032481 knots:

1639 feet per second = 971.08095032481 knots

Alternative conversion
