How it works
A cooking weight converter restates a recipe weight in a different unit, moving between grams and kilograms on the metric side, the smaller milligram, and ounces and pounds on the customary side. It reduces your figure to grams, a convenient base for kitchen quantities, then scales out to the unit you choose, so one mechanism handles scaling a recipe, translating between metric and imperial weights and reading international ingredient lists alike. This matters because recipes cross borders and measuring systems, and weight is where precision matters most, especially in baking. A European recipe lists grams; an American or British one lists ounces and pounds; a spice or leavening quantity may be a few grams that a customary recipe would render awkwardly in fractions of an ounce. Weighing ingredients is more accurate than measuring by volume, so serious bakers work by weight — but only if the units line up. A converter removes the fiddly arithmetic and the risk of a mis-scaled batch. The convert-through-grams method is used because every weight unit here has a fixed ratio to the gram — one ounce is about 28.35 grams, one pound is about 453.6 grams, one kilogram is exactly 1,000 grams — so pivoting through it keeps results consistent and needs only one factor per unit. Note that these are avoirdupois ounces and pounds, the standard for food, not the troy units used for precious metals. Home cooks, bakers, recipe developers and anyone following a foreign recipe rely on a cooking weight converter for dependable results.
Convert to grams via known factors, then to the target unit
The input is multiplied by its unit's fixed number of grams to express the weight in grams, then divided by the target unit's gram value to complete the conversion. The ounce and pound used are avoirdupois, each defined as a constant number of grams, and the metric units are exact powers of ten, so every unit has a fixed ratio to the gram, making the pivot exact for every pairing with one stored factor per unit.

Frequently asked questions
How many grams are in an ounce?
One avoirdupois ounce, the standard used for food, is about 28.35 grams. So 4 ounces of flour is about 113 grams, and a pound, being 16 ounces, is about 453.6 grams. To convert grams to ounces, divide by 28.35. Do not confuse this with the troy ounce used for gold and silver, which is heavier at about 31.1 grams and not used in cooking.
How do I convert grams to pounds?
Divide the gram figure by about 453.6 to get pounds, since one pound is about 453.592 grams. So 1,000 grams is about 2.2 pounds. To reverse it, multiply pounds by 453.6. For mixed pounds and ounces, convert the whole weight to grams first, then split as needed. Working through grams keeps recipe scaling clean and avoids awkward fractional-pound arithmetic.
Should I weigh ingredients instead of using cups?
For baking, weighing is usually more accurate than measuring by volume, because a cup of flour can vary widely depending on how it is scooped and settled, while its weight in grams is consistent. Many modern recipes give both. If you want repeatable results, a kitchen scale set to grams is the reliable choice, and this converter helps translate any recipe's weights into the unit your scale uses.
Is a cooking ounce the same as a fluid ounce?
No, and confusing them is a common mistake. A weight ounce, about 28.35 grams, measures mass, while a fluid ounce measures volume, about 29.57 millilitres in the US system. They happen to be similar numbers for water but differ for other ingredients. This converter handles weight ounces only; for liquid volumes in fluid ounces, cups or millilitres, use a volume converter instead.
Why convert cooking weights through grams?
The gram is a coherent metric base at a practical scale for kitchen quantities, and every weight unit here has a fixed, exactly defined ratio to it. Using the gram as the pivot means the converter needs only one factor per unit rather than a separate rule for each pair, keeps results exact, and matches the unit most modern recipes and kitchen scales use for precise, repeatable measurement.
