Baumer scales:
(1) light - for liquids lighter than water
(2) heavy - for liquids heavier than water
The specific gravity of the solutions is relative to a temperature of 60°F. This probably represented room temperature in France during the 18th Century when Baume lived.

specific gravity for a liquid heavier than water at 60°F =
= 145 / (145 - (Baume heavy scale reading in degrees))
Baume heavy scale reading in degrees =
= 145 - (145 / (specific gravity of liquid heavier than water)) =
= 145 * (1 - (1 / (specific gravity of liquid heavier than water)))
