The short answer: 87 kilograms comes to 191.8021681 lb. That is 87 multiplied by 2.204622622, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 87 kg, BMI works out to 34 at 1.60 m, 30.1 at 1.70 m, 26.9 at 1.80 m and 24.1 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 1.802 lb past 190 lb, so if you need a round figure to quote, 190 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 87 that shortcut gives 191.4 pounds, off by 0.4022 pounds or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
