3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Pa}& =\frac{1\cancel{\mathrm{Pa}}}{6,894.76\cancel{\mathrm{Pa}}}\times 1\mathrm{psi}\\ & =\frac{1}{6,894.76}\mathrm{psi}\\ & =0.000145037681\mathrm{psi}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{psi}& =\frac{6,894.76\cancel{\mathrm{Pa}}}{1\cancel{\mathrm{Pa}}}\times 1\mathrm{Pa}\\ & =\frac{6,894.76}{1}\mathrm{Pa}\\ & =6,894.76\mathrm{Pa}\end{array}$$
