Worked examples
Converting 5 kilogram-force per square centimeter
Multiply 5 by 735.55914. That gives 3,677.8 millimeters of mercury. A quick sanity check: one kilogram-force per square centimeter is larger than one millimeter of mercury, so the number should get bigger — and it does.
Converting 72 kilogram-force per square centimeter
72 × 735.55914 = 52,960.26 millimeters of mercury. Working backwards, 52,960.26 ÷ 735.55914 returns 72 kilogram-force per square centimeter, which confirms the factor is applied the right way round.
