149 kilograms is 328.4887707 lb. The exact arithmetic is 149 × 2.204622622 = 328.488770655 pounds, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
At 149 kg, BMI works out to 58.2 at 1.60 m, 51.6 at 1.70 m, 46 at 1.80 m and 41.3 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.
The result sits 1.511 lb short of 330 lb, so if you need a round figure to quote, 330 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 149 that shortcut gives 327.8 pounds, off by 0.6888 pounds or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
