How to convert kilograms to pounds
To convert kilograms to pounds, multiply by 2.2046. One kilogram equals about 2.2046 pounds, and that factor comes from the exact definition of the pound as 0.45359237 kg — 2.2046 is simply 1 ÷ 0.45359237. Use the live converter above to go either way between kg and lb.
For a quick mental estimate, double the kilograms and add a bit (roughly 10%): 70 kg → about 140 + 14 = 154 lb. The calculator gives the precise figure, 154.3 lb.
When you need to convert kilograms to pounds
Most countries weigh people and goods in kilograms, while the United States — and, for body weight, often the UK — uses pounds. That is why kg to lbs is one of the most searched conversions. Typical situations:
- Body weight: a set of scales or a health app shows kilograms, but you think in pounds (or the reverse).
- Gym and fitness: barbell plates, dumbbells and training programmes mix metric and imperial loads.
- Travel and baggage: airline allowances are given in kilograms, so US travellers convert their pounds to check the limit.
- Cooking and shipping: recipes and parcel weights that need switching between the two systems.
- Medicine: drug doses are calculated per kilogram of body weight, so a weight in pounds must be converted first.
Kilograms and pounds: what each unit is
The kilogram is the base unit of mass in the metric (SI) system, now defined through a fixed value of the Planck constant. The pound (lb) is the imperial and US customary unit of mass; the international avoirdupois pound is defined as exactly 0.45359237 kilograms. Because that definition is fixed, kg and lb convert exactly — any rounding is only in the decimals shown.
