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 645 feet per second into knots we have to multiply 645 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

645 ft/s → V(kt)

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

V(kt) = 645 ft/s × 0.59248380129641 kt

V(kt) = 382.15205183618 kt

The final result is:

645 ft/s → 382.15205183618 kt

We conclude that 645 feet per second is equivalent to 382.15205183618 knots:

645 feet per second = 382.15205183618 knots

Alternative conversion
