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 Long Tons
A long ton (UK ton, displacement ton) equals 2,240 pounds or exactly 1,016.0469088 kg. The standard ton in the United Kingdom and Commonwealth countries, it equals 20 long hundredweights of 112 lb each. Naval architecture and ship displacement are specified in long tons: the displacement of a warship or cargo vessel is the weight of water it displaces, expressed in long tons. The Titanic had a displacement of approximately 52,310 long tons. British agricultural, mining, and coal trade statistics from the 18th through mid-20th centuries used long tons exclusively.
