Megatonne: meaning, definitions and examples
๐
megatonne
[ หmษษกษหtสn ]
measurement unit
A megatonne (also known as a megaton) is a unit of mass equal to one million metric tonnes. It is often used in discussions of large quantities such as those encountered in environmental science, particularly in relation to carbon dioxide emissions. The term comes from the prefix 'mega-', which means one million, combined with 'tonne', which is a metric unit of mass equivalent to 1,000 kilograms. In geological contexts, megatonnes are also used to express the energy released from events such as volcanic eruptions or earthquakes.
Synonyms
megaton, million tonnes.
Examples of usage
- The volcano erupted with a force of several megatonnes of TNT equivalent.
- Global carbon emissions reached nearly 35 megatonnes last year.
- The bomb released energy equivalent to several megatonnes.

Etymology
The term 'megatonne' originates from the metric system, where 'mega-' is a prefix denoting a factor of one million. The word 'tonne' comes from the French term for a metric ton, which is used in many countries around the world to measure mass. The use of megatonnes became more prominent in the 20th century, especially during discussions of safety and environmental impacts related to nuclear weapons and climate change. The concept of measuring large quantities is crucial in fields such as environmental science and global energy discussions, where it helps quantify the impact of human activity on the planet. Over time, the megatonne has become a standard unit for reporting carbon dioxide emissions and other greenhouse gases, aiding in the formulation of international climate agreements and targets.
