Question
State the SI unit of density. Relate it with its cgs unit.
✓

Answer

SI unit of density = kg/ per cubic metre

cgs = g/ per cubic centi metre

1kg m per cubic $=\frac{1\text{kg}}{1\text{mcube}} =\frac{10000\text{g}}{(100\text{cm})}$ per cubic

$=\frac{1}{1000}\text{g cm}$ per minus cube

Thus, 1kg/ m per cubic = 10 per cube.
