Mate you are reading your hydrometer wrong.
Disregard the alcohol scale, it's not needed for what we do. ABV is calculated using your Original gravity (OG) inyour case 1.040 and the Final Gravity (FG) we'll say 1.010
There is a handy calculation in the excellent coopers instructions under the lid of the can. This is the only thing you should take notice of in those instructions. Also look at this site http://www.brewersfriend.com/abv-calculator/ and use the calculator for your Alcohol % calculations.
Add maybe 0.2% for priming sugar (carb drops) and add just one per 750ml bottle.
