About 120 kg in pounds
120 kg is 264.55 lb because the international avoirdupois pound is exactly 0.45359237 kg, so a kilogram is 2.20462262 lb. Multiplying is safer than dividing: 120 × 2.20462262 = 264.55, whereas using ÷ 0.45359 adds a second rounding.
In Britain, body weight is quoted in stones and pounds on a bathroom scale but in kilograms in a clinic, so this conversion gets used twice. 120 kg is 18.9 stone, which is how it would be said aloud, and 264.55 lb is what a fitness app will show.
The common shortcut of doubling and adding 10% gives 264.0 lb for 120 kg — within 1% at this size, which is fine for a suitcase and not fine for a shipping manifest. Use the full factor wherever money or a limit depends on the answer.
120 kg is also 120,000 g and 264.55 lb, and a scale that reads in stones shows 18.9 st. The three readings describe one weight, so when a delivery note, a gym app and a customs form disagree by a pound, the difference is rounding rather than an error.
Written without units, 120 kg in pounds is 264.55, and the nearest whole pound is 265 lb. Quoting the whole number is fine for luggage and body weight; keep the decimal for a shipping document or a prescription.
