Converting 144 kilograms gives 22 st 9.5 lb. One multiplication does it — 144 × 0.1574730444 = 22.6761183962 stones — and because the factor is defined rather than measured, that answer will not drift over time.
At 144 kg, BMI works out to 56.2 at 1.60 m, 49.8 at 1.70 m, 44.4 at 1.80 m and 39.9 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.
Plenty of people do this in their head: divide by 6.4 instead of using the exact factor 0.1574730444. At 144 that shortcut gives 22.5 stones, off by 0.1761 stones or about 0.78%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
