The Quarter in American Trade History
The US quarter (25 lbs) was a practical unit for retail and wholesale trade in the 18th-19th centuries. Flour, sugar, and grain were sold in quarter-hundredweight sacks. A "quarter of flour" (25 lbs) was the standard household purchase size. Market prices were quoted per quarter for retail and per hundredweight for wholesale. The unit declined as pre-packaged consumer goods in standardized sizes replaced bulk purchasing.
US Quarter vs UK Quarter: Different Units, Same Name
The US quarter = 25 lbs (¼ of 100 lbs short hundredweight). The UK quarter = 28 lbs (¼ of 112 lbs long hundredweight = 2 stone). In colonial and early American records, the distinction matters: a "quarter of wheat" in a New England ledger (US) is 25 lbs = 11.34 kg, while the same term in a British document means 28 lbs = 12.70 kg. Some historical British grain measurements use "quarter" as a volume measure (8 bushels), adding further confusion.
Modern Context: Where Quarters Still Appear
While largely obsolete, the quarter appears in: historical research and genealogy (trade records), traditional recipes ("quarter of butter" = 25 lbs for commercial bakeries), horse feed calculations (traditional horsemen may think in quarters), and antique scale markings. Understanding the quarter helps interpret primary source documents from the American agricultural era (1700s-early 1900s).
