Birx (BX) hydrometers is a hydrometer use for determining the
percentage of weight by sucrose. One degree Brix is 1 gram of
sucrose in 100 grams of solution and represents the strength of
the solution as percentage by weight (% w/w) (strictly
speaking, by mass). If the solution contains dissolved solids
other than pure sucrose, then the °Bx only approximates the
dissolved solid content. The °Bx is traditionally used in the
wine, sugar, fruit juice, and honey industries
