From it the analyst can compute the Original Extract which is the mass (grams) of sugar in 100 grams of wort (°P) by use of the Plato scale. The symbol will denote OE in the formulas which follow. --wikipedia I have created a simple tool, and made the source code open source, that will allow you to calculate original gravity. I also created a blog post saying how I did it.
