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 670.2 feet per second into knots we have to multiply 670.2 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

670.2 ft/s → V_(kt)

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

V_(kt) = 670.2 ft/s × 0.59248380129641 kt

V_(kt) = 397.08264362885 kt

The final result is:

670.2 ft/s → 397.08264362885 kt

We conclude that 670.2 feet per second is equivalent to 397.08264362885 knots:

670.2 feet per second = 397.08264362885 knots
