The Quarter in British Wool Trade
The UK quarter (28 lbs = 2 stone) was fundamental to the British wool trade from medieval times through the 19th century. Wool was weighed and taxed by the quarter, with a standard wool sack containing multiple quarters. The Woolsack in the House of Lords symbolizes this historical importance. Wool prices were quoted per quarter in markets from London to Yorkshire.
UK Quarter in the Imperial Weight System
The UK quarter fits neatly into the imperial hierarchy: 1 quarter = 2 stone = 28 lbs. Four quarters = 1 long hundredweight (112 lbs). Twenty long hundredweight = 1 long ton (2,240 lbs). This means 80 quarters = 1 long ton. The system was designed around factors of 4 and 7 (stone = 14 lbs), unlike the US system based on factors of 4 and 25.
Quarter as a Grain Volume Measure
Confusingly, "quarter" was also used as a volume measure for grain in Britain: 1 quarter = 8 bushels. The weight of a quarter (volume) varied by grain type: wheat quarter weighed about 480 lbs, barley about 384 lbs, oats about 312 lbs. Context in historical documents determines whether "quarter" refers to mass (28 lbs) or volume (8 bushels).
