| \(\large{ A_1 }\) = area 1 | \(\large{in^2}\) | \(\large{mm^2}\) |
| \(\large{ A_2 }\) = area 2 | \(\large{in^2}\) | \(\large{mm^2}\) |
| \(\large{ p_1 }\) = pressure 1 | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_2 }\) = pressure 2 | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
