A ton, metric ton or tonne is a unit of mass and occasionally of energy. It is equal to 1 megagram ( = 1000 kilograms).

Several of the references below are explicit uses of the S.I. metric unit. Otherwise it is not impossible that what is used is the US/Imperial unit ( = 2000 pounds).


Units of mass

  • A Borg scoutship had a mass of 2.5 million metric tons. (TNG: "I, Borg")
  • The Quarren facility was capable of producing 8,000 metric tons of tylium per second at 94% thermal efficiency. (VOY: "Workforce")


Units of energy

A ton is also a way of indicating the energy released by an explosion of one metric ton of TNT - 4.184 gigajoules. In the 20th century nuclear weapons were graded by megatonnage - by the millions of megagrams of TNT they equalled.
