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 396.5 knots into feet per second we have to multiply 396.5 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
396.5 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 396.5 kt × 1.6878098570997 ft/s
V(ft/s) = 669.21660834005 ft/s
The final result is:
396.5 kt → 669.21660834005 ft/s
We conclude that 396.5 knots is equivalent to 669.21660834005 feet per second:
