Ingredient Converter
Convert between cups, grams, tablespoons, teaspoons, millilitres, and ounces for everyday plant-based cooking.
Values are estimates. Density varies with brand, moisture, grating, packing and cooking state.
How the converter works
Pick an ingredient, enter an amount and a unit, and the converter shows the same amount in grams, ounces, cups, tablespoons, teaspoons and millilitres.
Converting between volume and weight needs to know how heavy the ingredient is, because a cup of oats and a cup of tahini weigh very different amounts. The converter uses a separate density for each ingredient.
When to trust the numbers
Treat the results as kitchen estimates, not laboratory measurements. Brand, moisture, how finely something is chopped and how firmly it is packed into the cup all change the weight.
Ingredients that are counted by the piece or sold by weight, such as a whole onion or a block of tofu, have no meaningful cup measurement, and the converter tells you so.

Frequently Asked Questions
Why does a cup of one ingredient weigh more than a cup of another?
Cups measure volume, not weight. Dense ingredients such as tahini or cooked beans weigh more per cup than light ones such as oats, so the converter uses a separate density for each ingredient.
Are these US or metric cups?
US cups and spoons: a cup is about 237 ml, a tablespoon about 15 ml and a teaspoon about 5 ml.
Why can't I convert some ingredients to cups?
Some ingredients are measured by the piece or by weight, like a whole onion. A cup measurement wouldn't tell you much, so the converter shows grams and ounces instead.
Should I weigh ingredients for baking?
Yes, when you can. Weight is more reliable than volume, especially for flours and starches, so use grams for baking and cups or spoons for everyday cooking.
