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 631.6 feet per second into knots we have to multiply 631.6 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

631.6 ft/s → V_(kt)

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

V_(kt) = 631.6 ft/s × 0.59248380129641 kt

V_(kt) = 374.21276889881 kt

The final result is:

631.6 ft/s → 374.21276889881 kt

We conclude that 631.6 feet per second is equivalent to 374.21276889881 knots:

631.6 feet per second = 374.21276889881 knots

Alternative conversion
