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 487.4 feet per second into knots we have to multiply 487.4 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

487.4 ft/s → V_(kt)

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

V_(kt) = 487.4 ft/s × 0.59248380129641 kt

V_(kt) = 288.77660475187 kt

The final result is:

487.4 ft/s → 288.77660475187 kt

We conclude that 487.4 feet per second is equivalent to 288.77660475187 knots:

487.4 feet per second = 288.77660475187 knots

Alternative conversion
