Ingredient weight converter
Choose an ingredient, amount and unit — the calculator will approximately convert cups, spoons or millilitres to grams.
How many grams are in a cup or spoon?
The same volume can weigh very differently depending on the ingredient. A 250 ml glass of water weighs about 250 g, while the same glass of wheat flour is only about 130 g. Volume therefore cannot simply be replaced by the same number of grams.
This converter uses average ingredient densities. For precise baking, kitchen scales are still the most reliable option.
Frequently asked questions
Is one cup always 250 ml?
In Baltic recipes a “glass” often means 250 ml. In English-language recipes a US cup is about 240 ml, so the calculator offers both units separately.
Why can flour weight vary?
Flour can be spooned in loosely or packed down. Flour type and moisture also affect density, so any volume-to-weight conversion is approximate.
