Balling is a standard for the measurement of the density of solutions expressed as a percentage of the weight of the solute on (grams of sucrose per 100 grams of solution). Degrees Balling (°B) is sometimes used as a substitute for degrees Plato (°P). However, the two are not equivalent since the Balling scale was calibrated at 17.5°C and not at 20°C as is the Plato scale.
The difference between the two scales is about 0.05% wt/wt units. Both degrees P and B are temperature dependent. Traditionally used in Europe, it has largely been replaced by the Plato scale.
