Worked examples
Converting 5 pounds-force
Multiply 5 by 444822.16. That gives 2,224,110.81 dynes. A quick sanity check: one pound-force is larger than one dyne, so the number should get bigger — and it does.
Converting 72 pounds-force
72 × 444822.16 = 32,027,195.63 dynes. Working backwards, 32,027,195.63 ÷ 444822.16 returns 72 pounds-force, which confirms the factor is applied the right way round.
