160 pounds is 72.5747792 kg. The exact arithmetic is 160 × 0.45359237 = 72.5747792 kilograms, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
At 72.5748 kg, BMI works out to 28.3 at 1.60 m, 25.1 at 1.70 m, 22.4 at 1.80 m and 20.1 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 2.425 kg short of 75 kg, so if you need a round figure to quote, 75 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 160 that shortcut gives 72.727273 kilograms, off by 0.1525 kilograms or about 0.21%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
