Converting 147 pounds gives 66.67807839 kg. One multiplication does it — 147 × 0.45359237 = 66.67807839 kilograms — and because the factor is defined rather than measured, that answer will not drift over time.
At 66.6781 kg, BMI works out to 26 at 1.60 m, 23.1 at 1.70 m, 20.6 at 1.80 m and 18.5 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 1.678 kg past 65 kg, so if you need a round figure to quote, 65 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 147 that shortcut gives 66.818182 kilograms, off by 0.1401 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
