The short answer: 148 pounds comes to 67.13167076 kg. That is 148 multiplied by 0.45359237, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 67.1317 kg, BMI works out to 26.2 at 1.60 m, 23.2 at 1.70 m, 20.7 at 1.80 m and 18.6 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 2.132 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 148 that shortcut gives 67.272727 kilograms, off by 0.1411 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
