unit:TON_Metric

The tonne (SI unit symbol: t) is a metric system unit of mass equal to 1,000 kilograms (2,204.6 pounds). It is a non-SI unit accepted for use with SI. To avoid confusion with the ton, it is also known as the metric tonne and metric ton in the United States[3] and occasionally in the United Kingdom. In SI units and prefixes, the tonne is a megagram (Mg), a rarely-used symbol, easily confused with mg, for milligram.
