<P> Baumé degrees (heavy) originally represented the percent by mass of sodium chloride in water at 60 ° F (16 ° C). Baumé degrees (light) was calibrated with 0 ° Bé (light) being the density of 10% NaCl in water by mass and 10 ° Bé (light) set to the density of water . </P> <P> Because of vague instructions or errors in translation a large margin of error was introduced when the scale was adopted . The API gravity scale is a result of adapting to the subsequent errors from the Baumé scale . The Baumé scale is related to the Balling, Brix, Plato and' specific gravity times 1000' scales . </P> <P> Before standardisation on specific gravity around the time of World War II the Baumé scale was generally used in industrial chemistry and pharmacology for the measurement of density of liquids . Today the Baumé scale is still used in various industries such as brewing, sugar beet processing, ophthalmics, starch industry, winemaking and printed circuit board (PCB) fabrication . It is also used for caustic in refining process . </P>

Baume is the term used to express the strength of
