Specific Gravity

To Convert Degrees Baume Into Specific Gravity

(1) For liquids heavier than water: Subtract the degree of Baume from 145 and divide into 145. The quotient is the specific gravity.

(2) For liquids lighter than water: Add the degree of Baume to 130 and divide it into 140. The quotient is the specific gravity.

To Convert Specific Gravity Into Degrees Baume

(1) For liquids heavier than water: Divide the specific gravity into 145 and subtract from 145. The remainder is the degree of Baume.

(2) For liquids lighter than water: Divide the specific gravity into 140 and subtract 130 from the quotient. The remainder will be the degree of Baume.
