Put 261 pounds into the exact factor of 0.45359237 and you get 118.3876086 kg. Written out: 261 × 0.45359237 = 118.38760857 kilograms, with no rounding applied until the final display.
At 118.388 kg, BMI works out to 46.2 at 1.60 m, 41 at 1.70 m, 36.5 at 1.80 m and 32.8 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 1.612 kg short of 120 kg, so if you need a round figure to quote, 120 kg is the honest nearest one.

Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
