Worked examples
Converting 5 kilopascals
Multiply 5 by 7.5006158. That gives 37.5031 millimeters of mercury. A quick sanity check: one kilopascal is larger than one millimeter of mercury, so the number should get bigger — and it does.
Converting 72 kilopascals
72 × 7.5006158 = 540.0443 millimeters of mercury. Working backwards, 540.0443 ÷ 7.5006158 returns 72 kilopascals, which confirms the factor is applied the right way round.
