The short answer: 286 pounds comes to 129.7274178 kg. That is 286 multiplied by 0.45359237, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 129.727 kg, BMI works out to 50.7 at 1.60 m, 44.9 at 1.70 m, 40 at 1.80 m and 35.9 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 0.2726 kg short of 130 kg, so if you need a round figure to quote, 130 kg is the honest nearest one. Plenty of people do this in their head: divide by 2.2 instead of using the exact factor 0.45359237. At 286 that shortcut gives 130 kilograms, off by 0.2726 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
