Density is defined as [(mass)/(volume)] expressed in [gram/cm3] or [kg/m3].
The definition is applicable to any homogeneous sample of gas, cheese, lead, rock, pea soup, glass ... anything.
In the SI system the unit is the Pascal (newton per square metre)
Other units regularly used are pound per square inch, bar and inches of Mercury
Pa (kPa)
The derived SI unit for density is Kilogram per cubic metre.
It is usually:kg per cubed-meterorkg per cubed-centimeterorg per cubed-centimeter(depending on which is most appropriate for what you are talking about)
Erg.
The official unit is kilograms per cubic meter; this unit is also often used in practice. It is also possible to use kilograms / liter or the equivalent gram / cubic centimeter. This unit gives numbers that are 1000 times smaller than kilograms / cubic meter.
Density is described by mass per unit volume.The equation for density is ρ = m/vwhere:ρ = densitym = massv = volumeThe SI unit is kg/m3 (this is widely used) or g/cm3The imperial (U.S.) unit is lb/ft3 or slugs/ft3Some useful conversions:1000 kg/m3 = 1 g/cm3 = 1000 g/L = 62.4 lb/ft3
kg/m3 - kilogramm / cubic meter
The derived SI unit for density is Kilogram per cubic metre.
It is usually:kg per cubed-meterorkg per cubed-centimeterorg per cubed-centimeter(depending on which is most appropriate for what you are talking about)
The unit to express power is YOUR MOMMA
density
the unit used to express power is time
Regardless of measurement system, it involves a unit of mass divided by a unit of volume. In SI for larger quantities, kg/m3 . For smaller ones, g/cm 3. In US units, lbs/in3 .
Hertz
There are many units that cannot be used to express a volume.There is something missing from your question to request the only unit.
An aerometer is an instrument used to measure the mass and density of gases.
Unit conversions express an amount in a different unit.
