The density of material shows the denseness of that material in a specific given area. The SI unit of density is kg/m³. For convenience, we use g/cm³ for solids, g/ml for liquids and g/L for gases.

1 Οκτ 2016 · Density is an SI derived unit. It is derived from the SI fundamental unit for mass, the kilogram, and the SI fundamental unit for length, the meter. Density is the mass per unit of volume. The SI derived unit for volume is cubic meters. So the derived SI unit for density is kg m3.
The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3 . One cubic centimetre (abbreviation cc) is equal to one millilitre.
Density can be defined as the mass of a material per unit volume. We had already learned that the unit of mass is Kilograms (Kg) and unit of vulume is Meter cube (m3). Since the defenition of density is mass per volume, the SI unit for density is kilogram per meter cube (kg/m3).
12 Απρ 2010 · The seven SI base units, which are comprised of: Length - meter (m) Time - second (s) Amount of substance - mole (mol) Electric current - ampere (A) Temperature - kelvin (K) Luminous intensity - candela (cd) Mass - kilogram (kg)
The SI derived units are expressed as products of powers of the base units, analogous to the corresponding relations between physical quantities but with numerical factors equal to unity. In the International System there is only one SI unit for each physical quantity.
28 Ιαν 2016 · The SI now consists of only two classes of units: base units and derived units. The radian and steradian, which were the two supplementary units, are now subsumed into the class of SI derived units. Thus the SI units are currently divided into base units and derived units, which together form what is called "the coherent system of SI units."
