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 669 feet per second into knots we have to multiply 669 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
669 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 669 ft/s × 0.59248380129641 kt
V(kt) = 396.3716630673 kt
The final result is:
669 ft/s → 396.3716630673 kt
We conclude that 669 feet per second is equivalent to 396.3716630673 knots:
669 feet per second = 396.3716630673 knots
