Understanding the Units
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
What is a Gram?
Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.
