Question

How is the SI unit of density derived? State CGS unit of density.

Answer 1

i. The SI unit of density is derived as follows :

Density = \(\frac{SI\,unit\,mass}{SI\,unit\,volume}\) 

= \(\frac{kg}{m^3}\) 

= kg m^-3

ii. CGS unit of density : g cm^-3

[Note : The CGS unit, g cm^-3 is equivalent to \(\frac{g}{mL}\) or g mL^-1.]
