Conversion Formula
g = Mt × 1000000000000
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.
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.
