How the conversion works
Cups measure volume and grams measure weight, so the conversion depends on how dense each ingredient is. A cup of flour weighs much less than a cup of honey. The converter uses an average density for each ingredient.
The formulas
Grams = cups × cup size (ml) × density (g/ml)
Cups = grams ÷ (cup size × density)
Worked example
How much does 1 US cup (240 ml) of all-purpose flour weigh? Flour has an average density of 0.507 g per ml.
- Volume: 1 × 240 = 240 ml.
- Weight: 240 × 0.507 = about 122 g.
Frequently asked questions
Why do different websites give different grams per cup?
Because it depends on how the cup is filled. Flour scooped straight from the bag can weigh 20% more than flour spooned in and leveled. The values here are typical averages; for precise baking, use a kitchen scale.
What's the difference between a US cup and a metric cup?
A US cup used in recipes and nutrition labels is 240 ml. A metric cup, common in Australia, Canada, and many Spanish-speaking countries, is 250 ml. Check where your recipe comes from.
How many tablespoons are in a cup?
There are 16 tablespoons in a cup, and 3 teaspoons in a tablespoon.
