Usually the density is determined, prefereably in the units g/cm³, kg/m³ and g/ml.
With alcoholometers usually the content of alcohol by volume in ethanol-water mixtures are determined.
Reference temperature is 20°C. Other reference temperatures are possible.
Calibration is generally made for 'reading below', for non-transparent liquids also 'reading above'.
