Density is a measure of how much mass an object has per a given volume. 2 And the dimensional formula of mass M 1 L 0 T 0. In some cases density is loosely defined as its weight per unit volume although this is scientifically inaccurate this quantity is more specifically called specific weight.
Density is a measure of relative compactness or how heavy an object is relative to its size.
R m V displaystyle rho frac mV where r is the density m is the mass and V is the volume. Scientists measure density in kilograms per cubic metre kgm3. For example the density of water is 1 gram per cubic centimeter. Density Equation for these Calculations.
