The short answer: 146 pounds comes to 66.22448602 kg. That is 146 multiplied by 0.45359237, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 66.2245 kg, BMI works out to 25.9 at 1.60 m, 22.9 at 1.70 m, 20.4 at 1.80 m and 18.3 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 1.224 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 146 that shortcut gives 66.363636 kilograms, off by 0.1392 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
