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 391 feet per second into knots we have to multiply 391 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
391 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 391 ft/s × 0.59248380129641 kt
V(kt) = 231.6611663069 kt
The final result is:
391 ft/s → 231.6611663069 kt
We conclude that 391 feet per second is equivalent to 231.6611663069 knots:
391 feet per second = 231.6611663069 knots
