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 646 knots into feet per second we have to multiply 646 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
646 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 646 kt × 1.6878098570997 ft/s
V(ft/s) = 1090.3251676864 ft/s
The final result is:
646 kt → 1090.3251676864 ft/s
We conclude that 646 knots is equivalent to 1090.3251676864 feet per second:
