Put 72 kilograms into the exact factor of 2.204622622 and you get 158.7328288 lb. Written out: 72 × 2.204622622 = 158.732828773 pounds, with no rounding applied until the final display.
At 72 kg, BMI works out to 28.1 at 1.60 m, 24.9 at 1.70 m, 22.2 at 1.80 m and 19.9 at 1.90 m. The healthy band tops out at 25, so the same weight can sit in three different categories depending on height — which is the whole limitation of the index.
The result sits 1.267 lb short of 160 lb, so if you need a round figure to quote, 160 lb is the honest nearest one. Plenty of people do this in their head: multiply by 2.2 instead of using the exact factor 2.204622622. At 72 that shortcut gives 158.4 pounds, off by 0.3328 pounds or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
