In most of the world, everything that is measured, is measured in SI units. Time, distance, mass, weight, area, volume and so on.
Unit of length is m and that of mass is kg Now volume is length x length x lenght. SO volume would have the unit mxmxm = m3 Density = mass / volume So unit for density = kg /m3
SI is a base 10 standardized system
Density is measured in units of mass divided by units of volume. The SI unit is kilograms/meter3.
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.
The product of pressure and volume has the same SI base units as energy or work, which is measured in joules (J). This is due to the definition of pressure (P) as force per unit area (N/m^2) and volume (V) as cubic meters (m^3), where the units of pressure times volume results in joules (J).
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
Volume is a fundamental quality because of volume per mass. Other familiar fundamental qualities include mass, velocity, speed, m3, cubic meter, and density.AnswerThere is no such thing as a 'fundamental unit' in SI. Units are either 'base units' or 'derived units'. In SI, volume is measured in cubic metres, where the metre is the base unit of length.

The SI unit for area is the square meter (m2), though hectare can also be used. One hectare equals 100 square meters.

Subsidiary quantities are derived quantities that are defined in terms of the base quantities in the International System of Units (SI), such as area and volume. Units for these quantities are formed by multiplying or dividing the base units according to their definitions. For example, the unit of speed, meter per second (m/s), is a derived unit formed from the base units of length (meter) and time (second) in SI.
Derived units do not have a single 'look'. They are produced from the base units of a measuring system such as the SI system.In the SI system there are seven base units which are;MetreKilogramSecondAmpereKelvinMoleCandelaAll other units are DERIVED units.For example the units for volume is the cubic metre and density is derived from the metre and kilogram. So density is kilograms per cubic metre in the SI system.
The base unit for volume is the cubic metre, because the units are cubed, the normal prefixes are a little confusing, so the non-SI unit litre is used for most everyday volumes. one cubic metre is 1000 litres.AnswerThere is no SI base unit for volume. Its unit is the cubic metre (m3), which is a derived unit.There are seven base units in SI, these being:metre (length)kilogram (mass)second (time)ampere (current)kelvin (temperature)candela (luminous intensity)mole (amount of substance)
There are , its m3
The International System of Units (SI) is based on seven base units: the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity. These base units are used to derive other units for quantities such as area, volume, and velocity.
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
