{"schema":"askedwell-answer-v1","url":"https://askedwell.com/pages/how-to-convert/kilograms-to-pounds","question":"How do I convert kilograms to pounds?","short_answer":"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.","long_answer":"**The conversion (defined exactly)**\n\n1 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.\n\n**Quick reference table (memorize these)**\n\n| Kilograms | Pounds (exact) | Cooking-rounded |\n|---|---|---|\n| 0.5 kg | 1.10 lb | 1.1 lb (~17.6 oz) |\n| 1 kg | 2.20 lb | 2.2 lb |\n| 1.5 kg | 3.31 lb | 3.3 lb (~3 lb 5 oz) |\n| 2 kg | 4.41 lb | 4.4 lb |\n| 2.5 kg | 5.51 lb | 5.5 lb |\n| 5 kg | 11.02 lb | 11 lb |\n| 10 kg | 22.05 lb | 22 lb |\n\n**Reverse: pounds to kilograms**\n\nDivide pounds by 2.205. Or use these mental shortcuts:\n- 1 lb ≈ 454 g (0.454 kg)\n- 5 lb ≈ 2.27 kg\n- 10 lb ≈ 4.54 kg\n- 50 lb ≈ 22.7 kg\n\n**Common cooking scenarios**\n\n- \"2 kg pork shoulder\" → 4.4 lb (typical bone-in shoulder weight)\n- \"1 kg flour\" → 2.2 lb (about 7-8 cups depending on packing)\n- \"500 g chicken breast\" → 1.1 lb (2 medium breasts)\n- \"1.5 kg whole chicken\" → 3.3 lb (small roaster)\n- \"3 kg ham\" → 6.6 lb (medium party ham)\n\n**Where precision matters**\n\nFor 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.\n\nFor COOKING (stews, roasts, soups): cooking-rounded 1 kg = 2.2 lb is fine. Recipes tolerate ±5% variance.\n\n**Cross-reference:** see /pages/how-to-convert/pounds-to-grams for finer-grained gram conversion + /pages/how-to-convert/ounces-to-grams for ounce-specific + /pages/how-to-convert/cups-to-grams for volume-to-weight.","ranges":[{"condition":"Quick mental conversion","duration":"< 5 seconds","note":"1 kg ≈ 2.2 lb (within 0.2%)"},{"condition":"Cooking-precise","duration":"5 seconds","note":"multiply kg × 2.205"},{"condition":"Baking-precise (4+ decimals)","duration":"10 seconds","note":"multiply kg × 2.20462 for sourdough/recipe scaling"}],"variables":[{"name":"Application precision","effect":"Cooking: ±5% fine (2.2).

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."},{"question":"Is the \"metric pound\" used in Europe the same as the US pound?","answer":"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."},{"question":"Can I weigh in either kg or lb for the same recipe?","answer":"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."}],"keywords":["kilograms to pounds","kg to lb","kg pounds conversion","metric to imperial weight"],"category":"cooking","date_published":"2026-05-21","date_modified":"2026-05-21","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
