Put 141 pounds into the exact factor of 0.45359237 and you get 63.95652417 kg. Written out: 141 × 0.45359237 = 63.95652417 kilograms, with no rounding applied until the final display.
At 63.9565 kg, BMI works out to 25 at 1.60 m, 22.1 at 1.70 m, 19.7 at 1.80 m and 17.7 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.
