$$ \begin{aligned} & \Ans \\ =& 3.8\ut{mm} \cdot \frac{1}{100} \\ =& 3.8\ut{mm} \cdot \frac{1\ut{m}}{1000\ut{mm}} \cdot \frac{1}{100} \\ =& \frac{38\cdot1\cdot1}{10\cdot1000\cdot100}\ut{m} \\ =& \frac{19}{500000}\ut{m} \\ =& 0.000038\ut{m} \\ =& 3.8\times 10^{-5}\ut{m} = 38\ut{\mu m} \end{aligned} $$
