The kg to lbs conversion factor
One kilogram equals 2.20462 pounds, so to convert kilograms to pounds you multiply by 2.20462: lb = kg × 2.20462. For example, 70 kg × 2.20462 = 154.32 pounds. To convert the other way, use the lbs to kg calculator.
For mental arithmetic, double the kilograms and add ten per cent: 70 doubled is 140, plus 14 is 154, which is within a third of a pound of the exact 154.32. The full factor is 2.2046226, and it follows from the international pound being defined as exactly 0.45359237 kg.
How to convert kilograms to pounds
Enter a weight in kilograms and the calculator multiplies by 2.20462 to give pounds. Great for body weight, luggage, and shipping. Round to two decimals for practical use.
Worked examples: an airline allowance of 23 kg is 50.7 lb, a 20 kg limit is 44.1 lb, and a 100 kg barbell loads to 220.5 lb. Gym plates run the other way — a 45 lb plate is 20.4 kg, not the round 20 kg of a metric plate.
The grams to ounces calculator handles the closely related case.
KG to lbs reference table
| Kilograms | Pounds |
|---|---|
| 1 kg | 2.20 lb |
| 10 kg | 22.05 lb |
| 70 kg | 154.32 lb |
| 100 kg | 220.46 lb |
Rounding to whole pounds is fine for luggage and body weight, but keep two decimals for anything sold by weight, where half a pound on a 25 kg sack is real money. It is also worth noting that kilograms measure mass while pounds are used loosely for both mass and weight; on Earth the distinction makes no practical difference.
