Unit of Density

The physical quantity called density is the mass per unit volume of any particular object. This quantity, also named Volumetric Mass Density can be measured in a number of ways, but the most commonly used metric is to calculate the density of the object is to divide the mass by is volume. 
  • Density equals m/v. 
Here m stands for the mass of the object while v stands for the volume. So density is to divide the mass in kg by its volume in cubic meters. The volume of any specific object can be calculated by determining the value of length * breadth * height. Unit of the physical quantity, density is kg/m^3. m^3 is the unit of volume while the unit of mass is kilogram (kg). 

The standardized value for the density of water is nearly 1000 kg/m^3 while the density of air is around 1.2 kg/m^3. Remember that if solids when placed in water and are found to sink, the density of that object is definitely greater than water.
