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.
About Pounds
The avoirdupois pound (lb) is the primary unit of weight in the United States and United Kingdom for everyday use, equal to 16 ounces or exactly 453.59237 grams. It dominates American life: body weight, grocery produce, deli counter cuts, freight shipping costs, gym weights, and building material quantities are all measured in pounds and ounces. American recipes use pounds for meat and large quantities. The pound derives from the Roman 'libra pondo' (a pound by weight) - hence both the symbol 'lb' (from libra) and the British currency symbol '£'.
