How to use Cooking Measurement Converter
- Choose the ingredient you are measuring.
- Enter the amount and select the unit you have, volume or weight.
- Read the equivalents in every other unit in the table.
- Weigh on a scale where possible for baking, using the result as a guide.
How the conversion works
Volume units are converted to millilitres, and weights are converted to grams. To move between them the tool uses a density for the chosen ingredient, stored as grams per US cup. Density in grams per millilitre is that figure divided by 236.588, and grams = millilitres × density.
Worked example: all-purpose flour is stored as 125 g per US cup. One cup is therefore 125 g, a tablespoon (14.79 ml, one sixteenth of a cup) is about 7.8 g, and 250 g of flour is about 2 US cups. Granulated sugar at 200 g per cup means 1 cup is 200 g and 100 g is half a cup.
Tips for accurate kitchen measuring
- Use a digital scale for baking whenever you can; it removes most of the variability.
- Spoon flour into the cup and level it off instead of scooping, which compacts it.
- Measure liquids in a jug at eye level, and dry goods in nested dry cups.
- Pack brown sugar firmly if the recipe says packed.
- Keep the recipe unit system consistent; do not mix cups and grams from different sources.
Limits of this table
The densities are typical published values and are rounded, so the tool shows approximate results. Actual weights change with brand, moisture, temperature, fineness and how the ingredient is packed. Fluid ounces are volume and ounces are weight, which are not interchangeable except roughly for water. Treat the numbers as a helpful starting point, and for delicate recipes such as bread, cakes and pastry follow the weights given by the recipe author. Nothing you enter leaves your browser.
Why use this cooking measurement converter tool
- 25 ingredients. Flours, sugars, fats, dairy, syrups, grains and common baking staples.
- US and metric cups. Compare a 236.6 ml US cup with the 250 ml cup used in many other countries.
- Volume and weight. Convert between cups or spoons and grams or ounces using ingredient density.
- Clear about accuracy. Values are approximate and labelled as such.
Frequently asked questions
How many grams are in a cup?
It depends on the ingredient. A US cup of all-purpose flour is about 125 g, granulated sugar about 200 g, butter about 227 g and water about 237 g. A cup measures volume, so denser or more tightly packed ingredients weigh more.
Why are cup measurements inconsistent?
Flour can be scooped, spooned or sifted and each method packs a different amount. Brands vary in density, and countries define a cup differently: 236.6 ml in the US, 250 ml in metric recipes. This is why many bakers prefer weighing.
Are tablespoons the same everywhere?
Not quite. The US tablespoon is about 14.8 ml, while many metric countries use 15 ml, and Australia uses 20 ml. The difference is small in a single spoonful but can add up. This tool uses the US teaspoon and tablespoon.
