Tonne
The tonne (/ t ʌ n / or / t ɒ n /; symbol: t) is a metric unit of mass equal to 1,000 kilograms. It is also referred to as a metric ton to distinguish it from the nonmetric unit. It is equivalent to approximately 2, pounds; short tons (US), and long tons (UK). The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass.
