97 kilograms is 15 st 3.8 lb. The exact arithmetic is 97 × 0.1574730444 = 15.2748853085 stones, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
At 97 kg, BMI works out to 37.9 at 1.60 m, 33.6 at 1.70 m, 29.9 at 1.80 m and 26.9 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.
