Pick the ingredient first, since the volume-to-weight conversion depends on it.
About This Tool
Why use Cooking Measurement Converter?
This cooking converter translates between cups, tablespoons, teaspoons, fluid ounces, millilitres, grams, ounces and pounds — and crucially, it does so per ingredient, because a cup is a measure of volume and a gram is a measure of weight.
That distinction is the whole point. One US cup of water weighs 240 g, but a cup of all-purpose flour is only 125 g and a cup of granulated sugar is 200 g. Convert 2 cups of flour and you get 250 g; convert 2 cups of sugar and you get 400 g. Any converter that gives the same answer for both is wrong.
Key Benefits
Ingredient-aware
Uses the real density of each ingredient, so flour, sugar, butter, honey and oil each convert correctly rather than sharing one generic factor.
Volume and weight in one place
Converts cups to grams, tablespoons to millilitres or ounces to cups without needing separate tools.
Common baking ingredients
Covers flours, sugars, butter, oats, rice, honey, cocoa and oil — the ingredients where getting the conversion wrong ruins the recipe.
How to use Cooking Measurement Converter
- 1
Pick the ingredient first, since the volume-to-weight conversion depends on it.
- 2
Enter the amount and choose the unit you are converting from.
- 3
Choose the unit you want, whether that is a volume or a weight.
- 4
For flour, spoon it into the cup and level it off rather than scooping, which is how the 125 g figure is defined.
Best use cases
Follow a US recipe using kitchen scales.
Convert a European recipe given in grams into cups.
Scale a recipe up or down without losing the ratios.
Switch to weighing flour for more consistent baking results.
How this tool compares
Cooking Measurement Converter FAQs
How many grams is one cup of flour?
One US cup of all-purpose flour is about 125 g when spooned into the cup and levelled off. Scooping the cup directly into the bag compacts the flour and can push it to 150 g or more, which is a common reason baked goods turn out dry.
Why is a cup of sugar heavier than a cup of flour?
Because the ingredients have different densities. Sugar granules pack together more tightly than flour particles, so the same volume holds more mass — 200 g of sugar against 125 g of flour. This is exactly why professional baking recipes use weight.
How many teaspoons are in a tablespoon?
Three teaspoons make one US tablespoon, which is about 14.8 ml. Note that the Australian tablespoon is 20 ml, or four teaspoons, so recipes from Australia need care when small quantities of raising agents are involved.
Is a US cup the same as a metric cup?
No. A US cup is 236.6 ml, while a metric cup used in Australia and New Zealand is 250 ml, and an old UK imperial cup was 284 ml. This converter uses US customary measures, which is what the large majority of online recipes assume.
Should I measure by weight or volume?
Weight, whenever you can. Scales remove the variation that comes from how tightly an ingredient is packed into a cup, which is the single biggest source of inconsistency in home baking. Volume is fine for liquids, where density is predictable.
