About the KG to LBS Converter
Since 1959 the international pound has been defined as exactly 0.45359237 kilograms, the factor NIST lists, so a kg to lbs conversion is one division with nothing rounded until the display. One kilogram is about 2.2046 lb, which is why the familiar shortcut is to multiply by 2.2; the shortcut runs about 0.2% low, so 100 kg comes out as 220 lb instead of 220.4623 lb. The converter also splits the answer into pounds and ounces, the way US scales, recipes and luggage limits often read. There are 16 ounces in a pound, so the fractional part of the pounds is multiplied by 16: 70 kg is 154.3236 lb, which is 154 lb and 5.18 oz. The ounces are rounded to two decimals, and a value that rounds to 16 ounces carries into the next whole pound. Grams are the kilograms times 1,000.
