Baumé scale

The Baumé scale is a pair of hydrometer scales developed by French pharmacist Antoine Baumé in 1768 to measure density of various liquids. The unit of the Baumé scale has been notated variously as degrees Baumé, B°, Bé° and simply Baumé (the accent is not always present). One scale measures the density of liquids heavier than water and the other, liquids lighter than water. The Baumé of distilled water is 0.

Conversions

The relationship between specific gravity (s.g.) (relative density) and degrees Baumé is function of the temperature. Different versions of the scale may use different reference temperatures. Different conversions formulae can therefore be found in various handbooks.

As an example, a recent handbook indicates the following conversion rules at a temperature of 60 °F (16 °C):

For liquids more dense than water:

For liquids less dense than water:

An older handbook gives the following formulae (no reference temperature being mentioned):
