Question

Which unit would you prefer to make the measurement of the thickness of your paper?

Answer 1

1. For measuring small lengths smaller units such as centimeter (cm), millimeter (mm), nanometer(nm), and micron(µ) are used.
2. Millimeter (mm) is one-thousandth part of a meter.
3. $1mm={10}^{-3}m$.

Hence, millimeter (mm) is used to measure the thickness of the paper.
