Conversion formula
The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:
1 kt = 1.6878098570997 ft/s
To convert 391 knots into feet per second we have to multiply 391 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:
1 kt → 1.6878098570997 ft/s
391 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 391 kt × 1.6878098570997 ft/s
V(ft/s) = 659.933654126 ft/s
The final result is:
391 kt → 659.933654126 ft/s
We conclude that 391 knots is equivalent to 659.933654126 feet per second:
391 knots = 659.933654126 feet per second
