Convert Metric Tons to Megatons
Convert Metric Tons (t) to Megatons (Mt) instantly and accurately.
Conversion Formula
Mt = t × 1.000000000e-6
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 Megatons
A megaton (Mt) equals one million metric tonnes (10⁹ kg). Nuclear weapon yields are measured in megatons of TNT equivalent: the largest weapon ever detonated, the Soviet Tsar Bomba tested in 1961, had a yield of approximately 50 Mt TNT and produced a fireball 8 km in diameter. Annual global CO₂ emissions are reported in gigatons (Gt), but regional emissions data and specific industrial sectors are quoted in megatons. The Chicxulub asteroid impact that caused the Cretaceous-Paleogene mass extinction released energy equivalent to roughly 100 million Mt of TNT.
