About Metric Tons
A metric ton (t), also called a tonne, equals exactly 1,000 kilograms. It is the standard large mass unit in the international SI system, used worldwide for shipping, trade, agriculture, industry, and environmental monitoring. Global steel production, grain harvests, CO₂ emissions, shipping freight, and oil production are all reported in millions of metric tonnes. A standard TEU shipping container can carry up to approximately 28 metric tonnes of cargo. Carbon footprint calculators express emissions in CO₂ equivalent tonnes (tCO₂e).
About Kilotonnes
A kilotonne (kt) equals 1,000 metric tonnes (10⁶ kg). In military and geopolitical contexts, nuclear weapon yields are expressed in kilotons of TNT equivalent (kt TNT): the atomic bomb dropped on Hiroshima had a yield of approximately 15 kt TNT. Environmental science uses kilotonnes for reporting regional greenhouse gas inventories, industrial pollutant releases, and annual waste generation. Mining operations quote ore extraction rates in kilotonnes per day. The global atmospheric inventory of various trace gases is reported in kilotonnes.
