Hello John You surprise me - I won't argue, but I've never before seen degrees used with Brix measures, only percentages. I've been using a refractometer for about 25 years, I've seen a lot of different documents on refractometers and Brix measures, and this was the first time I've seen degrees used. The visual scale in my refractometer and in others I've used is marked in percentages, not degrees. The manufacturers and suppliers I know of use percentages, not degrees:

We use Brix measures as an indicator of crop quality, but the references I have on ethanol production also use percentages, though Mike Nixon's The Compleat Distiller comes close: "There are many possible scales for measuring the density (and hence, the sugar content) of a solution. The most common include: Specific Gravity and degrees Plato, Brix or Ballings. The specific gravity of a solution is the ratio of its density to that of pure water. A specific gravity of 1.050, for example is 5 % denser than pure water. The Plato, Brix and Ballings scales all relate the density of the solution to the % sucrose by weight." But I'll take your work for it John.
