How it works
- Paste the ingredient list with its cups and spoons, one ingredient a line.
- Leave the cup size on automatic for US recipes, or choose a metric, UK, Japanese, Korean, Turkish or Brazilian cup.
- Every cup and spoon of a known ingredient is turned into grams; anything else is left as it was, with a note.
Frequently asked questions
- Why does a cup of flour weigh less than a cup of sugar?
- Because grams measure weight and cups measure volume: flour is light and airy (about 120 g a cup), sugar dense (198 g), honey heavier still (336 g). The converter uses each ingredient’s own figure.
- Where do the weights come from?
- From King Arthur Baking’s ingredient weight chart for baking staples and USDA FoodData Central for the rest. A cup is never filled quite the same twice, so take them as a close guide.
- How big is a cup?
- A US cup is 236.6 ml; a metric cup 250 ml; Japanese and Korean cups 200 ml; a Turkish su bardağı about 200 ml; a Brazilian xícara 240 ml. A tablespoon is 15 ml and a teaspoon 5 ml.
- What if an ingredient is not known?
- It is left in cups with a note. Liquids like water and milk convert almost one gram per millilitre.
- Is anything uploaded?
- No. It is worked out in your browser, and nothing you type leaves your computer.
