波美度°Bé 與比重換算
波美度= 144.3-(144.3/比重)
比重比水重的＝144.3/(144.3-波美度)
比重比水輕的＝144.3/（144.3+波美度）
比重 1.5 換算波美度:
144.3-(144.3/1.5)=48.1
波美度 30 度換算比重:
144.3/144.3-30 = 1.26
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 the other, liquids
lighter than water. The Baumé of distilled water is 0. The API gravity scale is
based on errors in early implementations of the Baumé scale.Based on concentration
of dry solids, it shows the amount of sweetness in a sweetener.

The relationship between specific gravity
(s.g.) (relative density) and degrees Baumé is function of the temperature.
Different versions of the scale may use different reference temperatures.
Different conversions formulae can therefore be found in various handbooks.
As an example, a recent handbook[1] states
the conversions between specific gravity and degrees Baumé at a temperature of
60 °F (16 °C):
Definitions
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.
Other scales
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.
Use
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.
