Worked examples
Converting 5 kilogram-force per square centimeter
Multiply 5 by 28.959018. That gives 144.7951 inches of mercury. A quick sanity check: one kilogram-force per square centimeter is larger than one inch of mercury, so the number should get bigger — and it does.
Converting 72 kilogram-force per square centimeter
72 × 28.959018 = 2,085.05 inches of mercury. Working backwards, 2,085.05 ÷ 28.959018 returns 72 kilogram-force per square centimeter, which confirms the factor is applied the right way round.
