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 Grams
The gram (g) is the basic metric unit of mass, equal to one thousandth of a kilogram. It is universally used in cooking, nutrition, postal services, and scientific measurement. Almost all food packaging worldwide shows nutritional information per 100 g. A US nickel coin weighs exactly 5 g, a teaspoon of sugar about 4 g, and a standard paperclip approximately 1 g. In chemistry, the gram is central to molar mass: one mole of carbon-12 atoms weighs exactly 12 g. Postal rates are typically scaled per gram or per 100 g.
