megatonnes
Million metric tons
Megatonnes is the metric spelling of megatons—units equal to one million metric tonnes, used primarily for measuring large quantities of materials or the explosive yield of nuclear weapons.
The metric spelling appears more commonly in scientific and international contexts: The country produces twelve megatonnes of steel annually.
In casual usage, megatonnes suggests enormous quantities: megatonnes of data.
