The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .

The kilogram (also spelled kilogramme [1]) is the base unit of mass in the International System of Units (SI), having the unit symbol kg. [1] ' Kilogram' means 'one thousand grams ' [ 2 ] and is colloquially abbreviated to kilo .
The units kilogram, gram, milligram, microgram, and smaller are commonly used for measurement of mass. However, megagram, gigagram, and larger are rarely used; tonnes (and kilotonnes, megatonnes, etc.) or scientific notation are used instead. The megagram does not share the risk of confusion that the tonne has with other units with the name "ton".
To handle these, Module:Convert/makeunits includes a specials table that adds an "alttype" (alternate type) field to certain whitelisted units. The alttype field allows conversion between units of different type, provided each unit is whitelisted to allow the conversion.
The kilogram (kg) is the unit of mass. The ampere (A) is the unit of electric current. The kelvin (K) is the unit of thermodynamic temperature. The mole (mol) is the unit of amount of substance. The candela (cd) is the unit of luminous intensity. The SI also defines 22 derived units and associated symbols:
