How do I convert kilograms to pounds?
1 kilogram (kg) = 2.20462 pounds (lb). For cooking, round to 1 kg = 2.2 lb (within 0.2%). To convert: multiply kg × 2.205. To reverse: 1 lb = 0.4536 kg, or divide lb by 2.205.
The full answer
The conversion (defined exactly)
1 kilogram = 2.20462262 pounds (avoirdupois). The kilogram is the SI base unit of mass; the pound is defined as exactly 0.45359237 kg per the 1959 international yard and pound agreement.
Quick reference table (memorize these)
| Kilograms | Pounds (exact) | Cooking-rounded |
|---|---|---|
| 0.5 kg | 1.10 lb | 1.1 lb (~17.6 oz) |
| 1 kg | 2.20 lb | 2.2 lb |
| 1.5 kg | 3.31 lb | 3.3 lb (~3 lb 5 oz) |
| 2 kg | 4.41 lb | 4.4 lb |
| 2.5 kg | 5.51 lb | 5.5 lb |
| 5 kg | 11.02 lb | 11 lb |
| 10 kg | 22.05 lb | 22 lb |
Reverse: pounds to kilograms
Divide pounds by 2.205. Or use these mental shortcuts: - 1 lb ≈ 454 g (0.454 kg) - 5 lb ≈ 2.27 kg - 10 lb ≈ 4.54 kg - 50 lb ≈ 22.7 kg
Common cooking scenarios
- "2 kg pork shoulder" → 4.4 lb (typical bone-in shoulder weight)
- "1 kg flour" → 2.2 lb (about 7-8 cups depending on packing)
- "500 g chicken breast" → 1.1 lb (2 medium breasts)
- "1.5 kg whole chicken" → 3.3 lb (small roaster)
- "3 kg ham" → 6.6 lb (medium party ham)
Where precision matters
For BAKING (sourdough hydration, dough percentages, brine concentrations): use exact 2.205 multiplier or work in grams natively. The 0.2% error of cooking-rounded ratios accumulates in multi-step recipes.
For COOKING (stews, roasts, soups): cooking-rounded 1 kg = 2.2 lb is fine. Recipes tolerate ±5% variance.

Time ranges by condition
| Condition | Duration | Note |
|---|---|---|
| Quick mental conversion | < 5 seconds | 1 kg ≈ 2.2 lb (within 0.2%) |
| Cooking-precise | 5 seconds | multiply kg × 2.205 |
| Baking-precise (4+ decimals) | 10 seconds | multiply kg × 2.20462 for sourdough/recipe scaling |
What changes the time
- Application precision. Cooking: ±5% fine (2.2). Baking: ±1% (2.21). Commercial scaling: exact (2.20462).
- Rounding strategy. Most home recipes round kg to 1 decimal (1.5 kg, 2.5 kg). Pounds rounded to 0.1 lb.
- Metric vs imperial recipe. If recipe lists both kg and lb, they may not match exactly due to rounding — use one consistently.
Common questions
Why does 1 kg equal 2.2 lb and not 2.0?
The pound is defined as 0.4536 kg, which makes the kilogram 1 / 0.4536 = 2.2046 pounds. It is not a clean ratio because the imperial pound was originally defined by historical artifacts (a brass standard kept in London), and the metric kilogram was originally defined as the mass of 1 liter of water. Two independently-defined systems do not produce clean conversion ratios.
Is the "metric pound" used in Europe the same as the US pound?
No. Informal use in Germany, Netherlands, parts of Scandinavia: "metric pound" or "pfund" = 500 g (exactly half a kilogram). US/imperial pound = 453.6 g. If a European recipe says "500 g" or "1 pfund," use 500 g — do NOT convert to 1 US pound. If it says "1 lb" with English context, it is 454 g.
Can I weigh in either kg or lb for the same recipe?
Yes, as long as you stay consistent. Weighing 1 kg flour for a recipe that calls for 1 kg flour: perfect. Weighing 2.2 lb flour for a recipe that calls for 1 kg: perfect (same amount). Where errors creep in: mixing-and-matching ("the recipe says 1 kg but I weighed 2 lb") — that is 0.2 lb (90 g) short, which matters for baking precision.
