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 649.1 feet per second into knots we have to multiply 649.1 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

649.1 ft/s → V_(kt)

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

V_(kt) = 649.1 ft/s × 0.59248380129641 kt

V_(kt) = 384.5812354215 kt

The final result is:

649.1 ft/s → 384.5812354215 kt

We conclude that 649.1 feet per second is equivalent to 384.5812354215 knots:

649.1 feet per second = 384.5812354215 knots

Alternative conversion
