The cubic meter.
The kilogram is the SI unit for mass.But grams are also often used.Additional AnswerIn SI, there are 'base' (not 'basic') units and 'derived' units -which, as the name suggests, are derived from the base units. There are seven base units, including the kilogram (not the gram) for mass.The SI unit for weight, which is the force due to gravity, is the newton, which is a derived unit.
a base unit is something that cannot be broken down further than it already is such as the Meter (m). There are 7 SI (International system of units) units and these are: Kilogram (kg) Meter (m) second (s) Ampere (A) Kelvin (K) Candela (cd) Mole (mol) Base units are base units because you cannot derive them further like you can other things like speed, volts, energy etc. Hope this helps (:
Base units need not have ANY volume. A second is the base unit for measuring time and it has no volume!
A Customary Unit or non-SI unit is a measurement unit that is not part of the metric system. Customary units are mainly units of the Imperial system but they could be localised customary units - such as Gaj (for area) is South Asia.
