Cartier degree
The Cartier degree , named after the French inventor and close colleague of Antoine Baumé Jean-François Cartier, was a unit of the relative density of liquids commonly used in France , mostly used to determine the alcohol content . Cartier changed the Baumé hydrometer around 1800 so that he only defined 15 subdivisions for liquids lighter than water at 16 ° Bé and he also moved the point for the relative density 1, at 11 ° Cartier, which corresponds to 10 ° Bé. This results in the following conversions for the relative density:
- For liquids heavier than water (at 12.5 ° C)
- Lighter than water for liquids (at 12.5 ° C)
