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 823.6 feet per second into knots we have to multiply 823.6 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

823.6 ft/s → V_(kt)

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

V_(kt) = 823.6 ft/s × 0.59248380129641 kt

V_(kt) = 487.96965874772 kt

The final result is:

823.6 ft/s → 487.96965874772 kt

We conclude that 823.6 feet per second is equivalent to 487.96965874772 knots:

823.6 feet per second = 487.96965874772 knots

Alternative conversion
