Concentration values that are calculated from the measured density (e.g. °Brix, % v/v alcohol, % w/w extract – these values will be available with upcoming v1.1) are automatically temperature-compensated to 20 °C (68 °F).
Density values (g/cm3, kg/m3) are not temperature-compensated.
For the calculation of SG (Specific Gravity), the sample's density value, compensated to 20 °C, is divided by the density of water at 20 °C. A temperature coefficient of 0.0003 g/cm3/K is applied in the temperature compensation of the sample's density value. This coefficient is typical for aqueous solutions.
