The short answer: 142 pounds comes to 64.41011654 kg. That is 142 multiplied by 0.45359237, the factor fixed by definition, carried to full precision before anything is rounded for display.
At 64.4101 kg, BMI works out to 25.2 at 1.60 m, 22.3 at 1.70 m, 19.9 at 1.80 m and 17.8 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 0.5899 kg short of 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 142 that shortcut gives 64.545455 kilograms, off by 0.1353 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
