The factor
1 kg = 2.20462 lb, from the exact definition 1 lb = 0.45359237 kg. To get pounds and ounces, multiply the decimal part of the pounds by 16: 3.5 kg = 7.716 lb = 7 lb 11.5 oz.
Quick estimates
Double the kilograms and add 10%: 70 kg × 2 = 140, plus 14 = 154 lb (exact: 154.3). To go back, halve the pounds and subtract 10%.
