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 quintal or centner is a historical unit of mass in many countries which is usually defined as 100 base units of either pounds or kilograms. It is commonly used for grain prices in wholesale markets in India, where 1 quintal = 100 kg.
