For the volumetric measurement, please see gross ton.

A ton, metric ton, or tonne was a unit of mass and occasionally of energy. It was equal to 1 megagram (1,000 kilograms).

Several of the references below are explicit uses of the SI metric unit. Otherwise, it is not impossible that what is used is the US/Imperial unit (2,000 pounds).

Units of mass Edit

  • The Quarren facility was capable of producing 8,000 metric tons of tylium per second at 94% thermal efficiency. (VOY: "Workforce")

Units of energy Edit

A ton was 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 in megatons - by the millions of megagrams of TNT they equaled.
