If I have the original gravity and final gravity of my hard cider (as measured by my hydrometer), do I determine the ABV using the same formula I would for beer?

Yes, sugar is sugar and yeast convert sugar to alcohol just the same in beer as in cider. (OG - FG) * .131 (or .135 or whatever).

Or, if you're unable to find the calculator application on your computer (Windows 8?), you can use Google to find an alcohol calculator like this one. – Tobias Patton Nov 5 '12 at 3:40
What are the .131 or .135 magic numbers? – Cleber Goncalves Mar 11 '13 at 17:04
I have been using .132, but I think the real number .1315 or something close... I also have seen another formula: (OG-FG) / 7.36 but I never used this one. – Philippe Dec 15 '15 at 22:01

While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes. - From Review – Mołot Mar 7 at 12:07
If you can read PHP and the application is right, one might extract the logic for calculating ABV, as well as logic for other brewing related things. Might be interesting to some, but this does not provide an answer. – Dale May 26 at 20:20
