## 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 feet per second into knots we have to multiply 670 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 ft/s → V(kt)

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

V(kt) = 670 ft/s × 0.59248380129641 kt

V(kt) = 396.96414686859 kt

The final result is:

670 ft/s → 396.96414686859 kt

We conclude that 670 feet per second is equivalent to 396.96414686859 knots:

670 feet per second = 396.96414686859 knots

## Alternative conversion
