Cooking emphasizes smaller-scale units including stone. Industrial adds metric tons and drops stone for cargo and batch sizes.

Mode
Showing milligrams through stone — ideal for recipes and UK body weight.
Tip: Type in any visible field; every unit updates from the same mass, so switching mode keeps the underlying conversion.
Pro Tip
Cooking mode hides metric tons and shows stone (common in the UK). Industrial mode hides stone and shows metric tons for bulk and freight. The underlying mass stays the same when you switch.

Weight Measurement Systems
The metric system uses grams and kilograms as base mass units; a metric ton is one thousand kilograms. US customary mass uses ounces and pounds (avoirdupois); a stone equals fourteen pounds and is still widely used for personal weight in the UK.
This tool converts through kilograms in the background so all seven units remain aligned when you edit any field or change mode.
Kilograms to Pounds: Complete conversion guide
Kilograms (kg) and pounds (lb) are the two most common units for body weight, shipping, and recipes across different regions. One kilogram is defined in the International System of Units (SI); the international avoirdupois pound is fixed at exactly 0.45359237 kg. That gives a conversion factor of approximately 2.20462262185 pounds per kilogram for exact work.
For mental math, 1 kg ≈ 2.2 lb is often close enough for everyday estimates. For nutrition labels, luggage limits, or commerce, use the full factor or this calculator to avoid rounding errors that add up over large quantities.
To convert kg to lb, multiply the value in kilograms by the factor above (or use our tool). To convert lb to kg, divide pounds by 2.20462… or multiply by 0.45359237. Always check whether the context uses avoirdupois ounces and pounds (default in the US and UK for weight) rather than troy units, which apply to precious metals.
Common pitfalls include confusing kilograms with pounds when reading dual-label products, and mixing up metric tons (1000 kg) with US short tons (2000 lb). Our converter keeps metric tons, stones, and smaller units in one place so you can validate cross-system weights in one pass.
Frequently Asked Questions
Exactly 1 / 0.45359237 ≈ 2.20462262185 pounds per kilogram for international avoirdupois pounds. For quick estimates, 2.2 is often used.
A stone is 14 pounds, used especially for body weight in the UK and Ireland. It is not typically used for cooking ingredients or industrial loads.
Historically different regions standardized different units. Today science and most countries use SI (kg, g); the US still uses customary units for many everyday applications. Conversion tools bridge the gap without relearning tables.
