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 1991 feet per second into knots we have to multiply 1991 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

1991 ft/s → V_(kt)

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

V_(kt) = 1991 ft/s × 0.59248380129641 kt

V_(kt) = 1179.6352483811 kt

The final result is:

1991 ft/s → 1179.6352483811 kt

We conclude that 1991 feet per second is equivalent to 1179.6352483811 knots:

1991 feet per second = 1179.6352483811 knots
