Here is the answer up front: 1 kilogram = 2.2 pounds. It is exact, it does not depend on what you are weighing, and it is the same figure professional kitchens and recipe developers use. The rest of this guide is the useful part around the number: a full table, three worked examples from real recipes, when to round and when not to, and the difference between the ounces on your kitchen scale and the ounces on a jewellery scale.

Kilogram Pounds
1 kilogram 2.2 pounds
5 kilograms 11 pounds
10 kilograms 22 pounds

How to convert kilograms to poundss

The conversion is a single multiplication, and the factor is exact: 2.2 pounds per kilogram, derived from the international definition of the pound (453.59237 g exactly) and the ounce (28.349523125 g exactly). Because the factor is exact, the only errors in practice come from rounding and from the scale. Rounding to 28 g per ounce or 454 g per pound is fine for soups, stews and roasts; for bread, pastry and anything with yeast or baking powder, keep the extra decimals and weigh to the gram. A digital scale that reads to 1 g is the best twenty dollars a baker can spend, and it makes every conversion on this page unnecessary — you simply weigh the ingredient in the unit the recipe already uses.

Why this conversion comes up

You will use this conversion in two directions, and they feel different. Converting a recipe into your scale's units is a one-off piece of arithmetic before you start. Converting a shopping quantity — a 1 kg bag of flour, a 500 g block of cheese — into the recipe's units is something you do while standing in the kitchen with the bag open. Both directions use the same factor, and both are covered in the table below, so you can find the number without doing the multiplication in your head.

Worked examples

Jam sugar, weighed not scooped

A jam recipe calls for 1 kilogram of sugar, and jam is one place where the sugar weight is not negotiable: too little and it will not set, too much and it is cloying. 1 kilogram is 2.2 pounds. Weigh the sugar on a scale in the unit the recipe uses — a cup of sugar can vary by 10 g depending on how it was scooped.

Meal-prep protein portions

Your meal plan calls for 2 kilogram of cooked chicken per portion, and you are prepping five portions: 10 kilogram, or 22 pounds of chicken to cook. Weigh the chicken after cooking, not before — meat loses about a quarter of its weight to cooking, and the plan's number is almost always a cooked weight.

A spice blend by weight

A spice blend recipe calls for 5 kilogram of paprika as its base, with smaller amounts of the other spices. 5 kilogram is 11 pounds. Weighing spices is more accurate than spooning them, especially for large batches, because a spoon of paprika can vary by a gram depending on how it was packed.

Practical guidance

The conversion also matters when you cook from two traditions at once. An American recipe, a British cookbook and a metric scale can describe the same dish in three different units, and the dish only works if all three agree. The fixed factor on this page is the bridge between them — but remember to check which pint, quart or gallon the recipe means, because the imperial versions are about 20% larger than the American ones.

Common mistakes to avoid

  1. Rounding to a 'nice' number in baking. Rounding to a 'nice' number in baking. 250 g rounded to 9 oz is fine for a stew; 250 g of flour rounded to 8 oz in a bread dough is a 7% error and the dough will feel it. Keep the extra decimals for baking.
  2. Converting volume to weight without the ingredient. Converting volume to weight without the ingredient. Grams and ounces are weight; cups and millilitres are volume. The conversion between them depends on density, so there is no universal factor — check the ingredient table for flour, sugar, butter and the rest.
  3. Trusting a spring scale for small amounts. Trusting a spring scale for small amounts. Spring scales are inaccurate below about 50 g. For spices, yeast and baking powder, use a digital scale that reads to 1 g, or measuring spoons.
  4. Using troy ounces instead of avoirdupois ounces. Using troy ounces instead of avoirdupois ounces. Kitchen scales use avoirdupois ounces (28.35 g); troy ounces (31.10 g) are for precious metals. If your scale has a troy setting, make sure it is off before weighing food.

Frequently asked questions

Can I convert kilograms to poundss for any ingredient?

Yes — this is a weight-to-weight conversion, so the ingredient does not matter. A gram of flour and a gram of sugar are both a gram. The ingredient only matters when you convert between weight and volume, for example grams to cups, because that depends on density.

Why does my scale show a different number from the conversion?

Usually because the bowl was not tared, the scale is set to the wrong unit, or the scale needs new batteries or recalibration. Tare the empty container, check the unit on the display, and test the scale with a known weight — a new 500 g bag of sugar is a convenient check.

Is 1 kilogram exactly 2.2 pounds?

Yes, by international definition. The pound is defined as exactly 453.59237 g and the ounce as exactly 28.349523125 g, so the factor 2.2 is exact to the precision shown. The table rounds to a sensible number of decimals for kitchen use; the rounding error is a fraction of a gram at the amounts cooks actually weigh.

Should I weigh ingredients or use cups?

Weigh them, whenever the recipe allows it. Weight is more accurate than volume, especially for flour, which can vary by 20 g per cup depending on how it is measured. A digital kitchen scale that reads to 1 g costs less than a set of measuring cups and removes every conversion on this page from your cooking entirely.

How much should I round the result?

For soups, stews, roasts and everyday cooking, two significant figures are plenty — 28 g for an ounce, 454 g for a pound. For baking, keep one more figure (28.35 g, 453.59 g) because rounding five ingredients by a gram or two each can move a dough by 10 g. Round once, at the end, never at each step.
