The short answer: 142 kilograms comes to 22 st 5.1 lb. That is 142 multiplied by 0.1574730444, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 142 kg, BMI works out to 55.5 at 1.60 m, 49.1 at 1.70 m, 43.8 at 1.80 m and 39.3 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 142 that shortcut gives 22.1875 stones, off by 0.1737 stones or about 0.78%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
