What is a Stone and a Quintal?
The stone (st) is a unit of mass in the British imperial system, defined as exactly 14 avoirdupois pounds. This is equivalent to approximately 6.35 kilograms.
The quintal (q) is a historical unit of mass, typically defined as 100 units of either kilograms or pounds, depending on the context. The metric quintal is precisely 100 kilograms.
Note: The Stone is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Quintal belongs to the imperial/US customary system.
History of the Stone and Quintal
The stone has historical roots in trade, where actual stones were used as weights. Its value varied significantly by commodity and region before being standardized at 14 pounds in Britain for general purposes.
The term derives from Arabic ("qinṭār") and Latin ("centenarius" meaning "containing a hundred"). It was widely used across Europe and its colonies, but its value varied significantly by region (sometimes being 100 pounds, sometimes 100 kilograms, or other values). The metric quintal (100 kg) is the most common modern interpretation.
