154 pounds works out to 69.85322498 kg. The calculation is 154 × 0.45359237, and the unrounded result is 69.85322498 kilograms, which is the number to use if this feeds into anything else.
At 69.8532 kg, BMI works out to 27.3 at 1.60 m, 24.2 at 1.70 m, 21.6 at 1.80 m and 19.3 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 0.1468 kg short of 70 kg, so if you need a round figure to quote, 70 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 154 that shortcut gives 70 kilograms, off by 0.1468 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
