Cooking measures volume and weight differently across regions. US recipes use cups, tablespoons, and teaspoons; metric recipes use milliliters and grams. Even a "cup" varies — US legal cup is 240 ml while metric recipes may assume 250 ml.
Our cooking converters focus on US customary kitchen units and their metric equivalents. For baking, weighing ingredients in grams is often more accurate than volume — but volume conversion still helps when scaling recipes quickly.
Professional bakers prefer grams for flour and sugar because scoop density varies. Home cooks can still use volume converters for sauces, oils, and liquids where small errors matter less. When doubling a recipe, convert each ingredient once and write down the metric amounts for reuse.

Common mistakes
