Convert cooking measurements, switch between cups and grams, and scale recipes with less guesswork.
Ingredient selection is needed for volume to weight conversions because density varies.
Weight is usually more reliable than volume for baking, and conversions between cups and grams depend on the ingredient.

This tool helps convert between common kitchen measurements and also scale ingredient lists up or down for different serving sizes.
When converting between volume and weight, the ingredient makes a difference. A cup of flour does not weigh the same as a cup of sugar, butter, or water.
Cooking and baking often mean switching between cups, tablespoons, teaspoons, grams, ounces, and millilitres. That can be awkward when a recipe comes from another country, uses a different measurement style, or needs to be adjusted for more or fewer servings.
This recipe measures calculator helps convert common kitchen units and scale ingredient lists with less manual maths. It is useful for baking, meal prep, international recipes, and everyday cooking.
Some recipes use metric units such as grams and millilitres. Others use cups, tablespoons, teaspoons, and ounces. This tool helps bridge those systems more easily.
Volume and weight are not the same thing. A cup measures how much space an ingredient occupies, while grams measure its mass. Because different ingredients have different densities, 1 cup of flour weighs considerably less than 1 cup of sugar, butter, or honey. This is why the ingredient must be specified when converting between cups and grams, and why two recipes calling for "1 cup" of the same ingredient can yield different weights if one packs the cup tightly and the other spoons it in loosely.
The table below shows the approximate gram equivalent of 1 US cup for common baking and cooking ingredients. Values are based on standard density measurements; flour in particular can vary slightly depending on whether the cup is scooped or spooned.
| Ingredient | 1 cup (US) in grams | Notes |
|---|---|---|
| Plain flour | ~130g | Varies with scooping technique |
| White sugar | ~200g | |
| Butter | ~227g | |
| Whole milk | ~244g | Also approximately 237ml by volume |
| Vegetable oil | ~218g | |
| Honey | ~331g | |
| Cocoa powder | ~142g | |
| Rice (uncooked) | ~189g | Long grain white rice |
| Water | 237g | Also 237ml; density 1 g/ml |
There are 16 US tablespoons in 1 US cup. This is one of the most frequently looked-up kitchen conversions and is useful when scaling recipes that give quantities in tablespoons rather than cups.

Recipe scaling is useful when halving a bake, doubling a favourite dish, or increasing quantities for guests. Instead of recalculating each ingredient manually, the scaling tab adjusts the whole list at once.
These differences matter most in baking, where small changes can affect texture, rise, and consistency.
For most baking recipes, grams are the better choice because they are more precise than cups. Volume measurements can vary depending on how ingredients are packed, scooped, or levelled.
A digital kitchen scale is often the simplest way to improve consistency for cakes, bread, cookies, pastry, and other bakes.
There are 16 tablespoons in 1 US cup.
Cups measure volume while grams measure weight. Different ingredients have different densities, so 1 cup of flour does not weigh the same as 1 cup of sugar or butter.
Grams are usually better for baking because weight measurements are more precise and consistent than volume measurements.
Yes. The recipe scaling tab can halve, double, triple, or multiply ingredient quantities by any factor entered.
No. US and UK cup measurements differ, which is one reason recipe conversions can affect baking results.
