Question

State the CGS unit and SI unit of mass? How are they related?

Answer 1

Step 1: SI unit of mass:

1. The SI unit of mass is the kilogram (kg).
2. A kilogram is equal to the mass of the international prototype of the kilogram kept at the Bureau of International Weights and Measures.

Step 2: CGS unit of mass:

1. For measuring light masses smaller units are used such as gram (g), milligram (mg)
2. The CGS unit of mass is gram (g).

Step 3: Relation between Kilogram and Gram:

1. $1g=\frac{1}{1000}kg={10}^{-3}kg$
2. $1mg=\frac{1}{1000}g={10}^{-3}g$

Hence, the SI unit of mass is the kilogram (kg) and the CGS unit of mass is the gram (g).
