Liquids heavier than water like must or wort have a specific gravity greater than 1. Distilled water has a specific gravity of 1. Brix or degrees Plato values come from the use of a refractometer. You will need to use this conversion calculator to convert the Brix values from the refractometer to specific gravity SG that is the most common value used in beer making.

Improve this answer. Community Bot 1. Thanks for the detailed answer. As you cleary point out, I should calculate the percentage of sugar in the total solution and not relative to the amount of water. And it makes sense. The difference between Brix and Plato is negligible, the differ after about the 3rd decimal place, but they're so close that they can be used interchangeably.
They were all arrived at through similar methods, but with differing degrees of accuracy. Custodian Custodian 10 10 bronze badges. Sign up or log in Sign up using Google.
Why would you want to? Just like the specific gravity of wort is compared to the specific gravity of water, the water is just an arbitrary variable that always gives us the same values each time we measure against it adjusted for the temperature of course.
Since we are using the hydrometer to measure degrees Plato and specific gravity , a correction factor must be applied for variations in temperature for both readings. The original idea for measuring the fermentables was presented by Karl Balling in , but was improved upon by the German Fritz Plato. Both are so close that we can consider them identical.
