What is density ?

What is density?  Density is important in terms of quantity calculations and correct operation of the purifier; it is also an indicator of the energy and ignition quality of the fuel oil. •     Density is the relationship between mass and volume at a given temperature and the unit is kg/m3. The standard reference temperature used in international trade for density calculation of petroleum products is 15°C. Applying this density at 15°C to the volume gives the weight in vacuum. •     The relationship between density and weight factor in air for fuel oils is approximately 1.1 kg/m3. To convert density at 15°C to the weight factor in air at 15°C, 1.1 kg/m3 should be deducted.
