141 kilograms is 310.8517897 lb. The exact arithmetic is 141 × 2.204622622 = 310.851789681 pounds, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
At 141 kg, BMI works out to 55.1 at 1.60 m, 48.8 at 1.70 m, 43.5 at 1.80 m and 39.1 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.
The result sits 0.8518 lb past 310 lb, so if you need a round figure to quote, 310 lb is the honest nearest one. Plenty of people do this in their head: multiply by 2.2 instead of using the exact factor 2.204622622. At 141 that shortcut gives 310.2 pounds, off by 0.6518 pounds or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
