3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{mile}& =\frac{1,609.344\cancel{\mathrm{m}}}{0.000001\cancel{\mathrm{m}}}\times 1\mathrm{um}\\ & =\frac{1,609.344}{0.000001}\mathrm{um}\\ & =1.609344\times 10^9\mathrm{um}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{um}& =\frac{0.000001\cancel{\mathrm{m}}}{1,609.344\cancel{\mathrm{m}}}\times 1\mathrm{mile}\\ & =\frac{0.000001}{1,609.344}\mathrm{mile}\\ & =6.21371192\times 10^{-10}\mathrm{mile}\end{array}$$
