About Quarters
A quarter (qr) in the avoirdupois system equals 28 pounds or one quarter of a hundredweight - approximately 12.70 kg. Historically, quarters were used in British trade for measuring grain, wool, and other bulk commodities. The British quarter of grain (28 lb) was the standard purchase quantity at markets and mills throughout medieval and early modern England. In the US, the term 'quarter' sometimes refers to a quarter of a short hundredweight (25 lb) rather than the British 28 lb.
About Gigatons
A gigaton (Gt) equals one billion metric tonnes (10¹² kg). It is the standard unit for planetary-scale mass measurements and global environmental budgets. Annual human CO₂ emissions are approximately 37 Gt CO₂; Earth's atmosphere contains roughly 5,480 Gt of air; Antarctic ice sheet mass is around 26,500,000 Gt of ice. Climate scientists report ice sheet mass balance changes in gigatons per year - the Greenland ice sheet loses approximately 280 Gt of ice annually due to climate change.
