I'm probably being thick but I can't fathom these things out lol:lol:
 
You'll need to use conversion charts for post-ferment readings from a refractometer. I use a refractometer during mash and boil and hydrometer during ferment for this reason (and for being able to taste samples). They're both fairly easy to use once you know what you're looking at. Just be sure to test either with water first to read 1.000 (or account for any variance).
 
Have you had a look at the how to guide on the forum?

If you've still questions ask again as they are really useful, letting you work out the strength of your brew as well as confirming fermentation has stopped.

Plan B is leave your FV alone for at least 2 preferably 3 weeks before bottling and stop drinking that brew when you start to feel, I believe the scientific term using this method is, "wobbly". :whistle:
 
This is a good guide on how to read a hydrometer.

Its just a floating ruler, the higher it floats the more sugar is present, as the sugar turns to alcohol the ruler starts to sink as alcohol is "less denser" than sugar saturated water, taking measurements as you start and finish lets you work out your alcohol content.
