Converts Brix to Specific Gravity and Specific Gravity to Brix. Some hydrometers have only one or the other, which is where this calculator comes in. Computes potential alcohol by volume (for use in dry wines). The Plato and Balling scale are very close to the Brix scale and can be used here interchangeably. The higher the number, the more sugar is in solution. Ultimately this translates into a higher alcohol volume in the finished product.
