Converting 98 kilograms gives 15 st 6.1 lb. One multiplication does it — 98 × 0.1574730444 = 15.4323583529 stones — and because the factor is defined rather than measured, that answer will not drift over time.
At 98 kg, BMI works out to 38.3 at 1.60 m, 33.9 at 1.70 m, 30.2 at 1.80 m and 27.1 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 98 that shortcut gives 15.3125 stones, off by 0.1199 stones or about 0.78%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
