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 389.9 feet per second into knots we have to multiply 389.9 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
389.9 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 389.9 ft/s × 0.59248380129641 kt
V(kt) = 231.00943412547 kt
The final result is:
389.9 ft/s → 231.00943412547 kt
We conclude that 389.9 feet per second is equivalent to 231.00943412547 knots:
389.9 feet per second = 231.00943412547 knots
