Baumé hydrometer scale

Baumé hydrometer scale

[bō′mā hī′dräm·əd·ər ‚skāl]
(physical chemistry)
A calibration scale for liquids that is reducible to specific gravity by the following formulas: for liquids heavier than water, specific gravity = 145 ÷ (145 -n) [at 60°F]; for liquids lighter than water, specific gravity = 140 ÷ (130 + n) [at 60°F]; n is the reading on the Baumé scale, in degrees Baumé; Baumé is abbreviated Bé.
