Answer 2

Answer:

1 Kg/m³ = 10^-3 g/cm³

1 g/cm³ = 1000 Kg/m³

Explanation:

Unit of density = Unit of mass/Unit of volume

In S.I system, unit of mass is Kg and unit of volume is m³. so S.I unit of density is Kg/m³. In C.G.S system, the unit of mass is g and unit of volume in cm³, so C.G.S unit of volume is g/cm³.

Relationship between S.I and C.G.S units :-

1 Kg/m³ = 1Kg/1m³

• 1000g/100cm³
• 1/10000 g/cm³

Thus,

=> 1 Kg/m³ = 10^-3 g/cm³

=> 1 g/cm³ = 1000 Kg/m³
