Density in CGS system is = 4 gms/ cm³
Unit of length = 1 cm unit of mass = 1 gm
Another system of units:
unit of mass = gm' = 100 gm
unit of length = cm' = 10 cm
=> 1 gm
and 1 cm
= Substitute these values in the value of the density.
Now density of the material:
Thus in the new system the value of density will be 40 units.
