Brix% is calibrated to the number of grams of cane sugar contained in 100g of cane sugar solution
Shows the concentration percentage of the soluble solids content (total solids) of a sample (water solution)
Soluble solids content is the total of all the solids dissolved in the water, ie. sugar, salts, protein, acids, etc. and the measurement reading value is the value of the sum total of those
When measuring a sugar solution, the Brix% should perfectly match the actual concentration
With solutions of other components, a conversion chart is required
