The Baumé scale is a pair of hydrometer scales developed by French pharmacist Antoine Baumé in 1768 to measure density of various liquids. The unit of the Baumé scale has been notated variously as degrees Baumé, B°, Bé° and simply Baumé (the accent is not always present). One scale measures the density of liquids heavier than water and ...
Hydrometers in the U.S. had been manufactured and distributed widely with a modulus of 141.5 instead of the Baumé scale modulus of 140. The scale was so firmly established that, by 1921, the remedy implemented by the American Petroleum Institute was to create the API gravity scale, recognizing the scale that was actually being used.
Comparable scales for indicating sucrose content are: the Plato scale (°P), which is widely used by the brewing industry; the Oechsle scale used in German and Swiss wine making industries, amongst others; and the Balling scale, which is the oldest of the three systems and therefore mostly found in older textbooks, but is still in use in some ...
He devised many improvements in technical processes, e.g. for bleaching silk, dyeing, gilding, purifying saltpetre, etc., but he is best known as the inventor of the Baumé scale hydrometer or "spindle" which provides scientific measurements for the density of liquids. The scale remains associated with his name but is often improperly spelt ...

On this scale, a specific gravity of 1.000 is reported as 0, and a specific gravity of 2.000 is reported as 200. [1] For example, concentrated sulfuric acid with a specific gravity of 1.8 has a Twaddell scale measurement of 160, reflecting the linear relationship between readings and specific gravity. The Twaddell scale is used exclusively for ...

Degree Baumé, a pair of density scales; Degree Brix, a measure of sugar concentration; Degree Gay-Lussac, a measure of the alcohol content of a liquid by volume, ranging from 0° to 100° Degree proof, or simply proof, the alcohol content of a liquid, ranging from 0° to 175° in the UK, and from 0° to 200° in the U.S.
