About Scruples
A scruple (s ap) is a unit of the apothecary weight system equal to 20 grains or approximately 1.296 grams. Derived from the Latin 'scrupulus' (a small sharp stone used as a counterweight), it was the basic dispensing unit in pre-metric pharmacy across Europe. The apothecary system divided the fluid ounce into 8 drams, each dram into 3 scruples, and each scruple into 20 grains - a hierarchy memorised by every 19th-century pharmacist.
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.
