The tonne (non-preferred SI derived unit; SI symbol: t), commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.10 short tons (US) or 0.984 long tons (imperial). Although not part of the SI per se, the tonne is "accepted for use with" SI units and prefixes by the International Committee for Weights and Measures, along with several other units like the bar, litre and day.

The long or imperial hundredweight of 8 stone (112 lb or 50.802345 kg) sees informal use in the imperial system but according to Schedule 1, Part VI of the Weights and Measures Act 1985, is no longer to be used for trade after the Act came into force.
