Cooking Measurement Converter

A cup measures volume, while grams measure weight (mass). Different ingredients have different densities — for example, 1 cup of flour weighs about 125g, while 1 cup of butter weighs about 227g. This is because butter is much denser than flour. That's why using an ingredient-specific converter is essential for accurate baking results.

One US cup of all-purpose flour weighs approximately 125 grams (or about 4.4 ounces). However, this can vary slightly depending on how the flour is measured. Professional bakers recommend using the spoon-and-level method or, even better, weighing ingredients with a kitchen scale for the most consistent results.

Fluid ounces (fl oz) measure volume — commonly used for liquids like water, milk, or oil. Ounces (oz) measure weight — used for solid ingredients like flour, sugar, or butter. In US cooking, 1 cup = 8 fluid ounces (volume), but 1 cup of flour weighs only about 4.4 ounces (weight). This converter handles both types and automatically applies the correct conversion based on the ingredient you select.

To convert cups to grams, you need to know the ingredient's density (grams per cup). The formula is: grams = cups × density (g/cup). For example, if 1 cup of brown sugar = 220g, then 2 cups = 440g. Our converter does this automatically — just select your ingredient, enter the amount, and choose your units. You can also find common densities in the reference table above.

Measuring by weight (grams/ounces) is far more accurate than measuring by volume (cups). A cup of flour can vary by up to 30% depending on how it's scooped, leading to inconsistent baking results. Professional bakers and pastry chefs around the world use weight measurements. If a recipe only provides volume measurements, use this converter to translate them into precise weight equivalents.

• 1 US cup = 16 tablespoons = 48 teaspoons = 8 fluid ounces ≈ 236.6 milliliters
• 1 tablespoon = 3 teaspoons ≈ 14.8 milliliters
• 1 teaspoon ≈ 4.93 milliliters
• 1 fluid ounce ≈ 29.57 milliliters
• 1 ounce (weight) ≈ 28.35 grams
• 1 pound = 16 ounces ≈ 453.6 grams
• 1 kilogram = 1000 grams ≈ 2.2 pounds ≈ 35.3 ounces
