Cooking Unit Converter
Convert cups, grams, ounces, and milliliters with smart ingredient density.
Densities are typical published values. Real ingredients vary slightly with brand, scoop method, and humidity. For baking, weighing is always more accurate than measuring by volume.
About this tool
Most converters get cooking wrong because they assume 1 cup of flour weighs the same as 1 cup of sugar. It doesn't. This converter has density data for the most common baking and cooking ingredients, so a cup of flour is 120g, a cup of sugar is 200g, and a cup of butter is 227g — accurately.
How to use it
- Pick the ingredient (or 'water' for general liquid conversion).
- Enter an amount and choose the source unit.
- Pick the target unit. The converter applies the right density automatically.
FAQ
Why does ingredient choice matter?+
Volume measures (cups, tablespoons) and weight measures (grams, ounces) only line up when you know the density of what's being measured. A cup of flour weighs about 120g; a cup of honey weighs about 340g. Picking the right ingredient gives you the right answer.
What if my ingredient isn't listed?+
Pick the closest match — a similar grain or sugar usually works. For accuracy, weigh the ingredient instead of measuring by volume.
