Cooking Measurement Converter
Convert cups, grams, ounces, tablespoons and millilitres for common baking ingredients — with ingredient-aware cups-to-grams.
Cups to grams, the accurate way
Recipes love to mix units — American sites measure flour in cups, European ones in grams, and your scale only speaks one language. This converter bridges them. Because a cup is a volume and a gram is a weight, the only honest way to convert between them is to know what's in the cup, so you pick the ingredient and the math follows its density.
How to use it
- Type the amount and choose the unit you have.
- Pick the unit you want — grams, cups, ounces, millilitres and more.
- Choose the ingredient so cups-to-grams (and back) is accurate.
Converting volume to volume (cups to tablespoons) or weight to weight (grams to ounces) doesn't depend on the ingredient, so the choice only matters when you cross between the two.
Frequently asked questions
Why do I have to choose an ingredient?
Cups measure volume and grams measure weight, and a cup of flour weighs far less than a cup of honey. To convert between volume and weight the tool needs the ingredient's density, so picking 'flour' or 'sugar' gives an accurate cups-to-grams result.
How accurate are the conversions?
They use standard kitchen densities (for example, 1 US cup of all-purpose flour ≈ 125 g). Real ingredients vary with how you scoop, sift or pack them, so treat the numbers as reliable baking estimates rather than lab measurements.
Which cup size does it use?
The US customary cup (236.6 ml). If you're using a metric cup (250 ml) or an imperial cup, your totals will differ slightly. Tablespoons and teaspoons are US sizes too.
Is anything sent to a server?
No. Every conversion is arithmetic that runs in your browser, so it works offline and keeps your recipes private.
