  • 1 US cup = 236.59 ml = 16 tablespoons = 48 teaspoons
  • 1 US tablespoon = 14.79 ml = 3 teaspoons
  • 1 US teaspoon = 4.93 ml
  • 1 litre = 1000 ml = 4.23 US cups

Cups to Grams by Ingredient

Converting cups to grams is ingredient-dependent because different ingredients have different densities. A cup of flour weighs much less than a cup of honey. Here are the most common ingredients:

Why Weight is More Accurate Than Volume

Professional bakers always measure by weight, and here's why: a cup of flour can vary by up to 30% depending on how it's measured. Scooping directly from the bag compacts the flour, while spooning and levelling gives a lighter cup.

With a kitchen scale, 125g of flour is always 125g of flour — no variation, no guesswork. This consistency is especially important in baking, where small differences can affect the final result.

Frequently Asked Questions

How many grams are in an ounce?
1 ounce equals 28.35 grams. This is a weight conversion that applies to all ingredients equally.
How many ml are in a US cup?
1 US cup equals 236.59 ml. Note that UK cups (284 ml) and metric cups (250 ml) are different sizes.
How do I convert cups to grams?
Cups to grams conversions depend on the ingredient because different ingredients have different densities. For example, 1 cup of flour weighs 125g, while 1 cup of sugar weighs 200g. Use our ingredient-specific converter for accurate results.
What is the difference between weight and volume measurements?
Weight (grams, ounces, pounds) measures how heavy something is, while volume (cups, ml, litres) measures how much space it takes up. Weight is more accurate for baking because the same volume of different ingredients can weigh very different amounts.
