A cups to grams converter translates volume-based cooking measurements into precise weights, accounting for the unique density of each ingredient. Because a cup of flour (125 g) weighs far less than a cup of honey (340 g), generic conversions lead to inaccurate recipes. This tool uses ingredient-specific density data so you get exact gram, ounce, and milliliter equivalents every time — essential for baking where precision matters most.

How to Use the Cups to Grams Converter
Converting cooking measurements accurately is one of the most common challenges home bakers and cooks face. Recipes from different countries use different measurement systems — American recipes rely on cups and tablespoons, while European and professional recipes typically use grams and milliliters. Our cups to grams converter bridges this gap by providing ingredient-specific conversions that account for the unique density of each ingredient.
To use this converter, start by selecting your ingredient from the dropdown menu. This is the most important step because the same volume of different ingredients can vary dramatically in weight. For example, one cup of honey weighs 340 grams, while one cup of cocoa powder weighs just 86 grams — a nearly fourfold difference. Next, enter the amount you want to convert, choose your starting unit (cups, tablespoons, teaspoons, grams, ounces, or milliliters), and select the unit you want to convert to. The result appears instantly as you type.
The quick reference table below the converter updates automatically when you select a new ingredient. It shows the most commonly needed conversions at a glance — from quarter cups to full cups, plus single tablespoon and teaspoon amounts. This is especially useful when you are scaling a recipe up or down and need to see several conversions at once.
For the most accurate results when baking, professional pastry chefs and serious home bakers strongly recommend measuring ingredients by weight rather than volume. A kitchen scale that reads in grams is one of the most valuable tools you can own. Volume measurements like cups can vary depending on how you scoop the ingredient, how tightly it is packed, and even humidity levels. A cup of flour measured by the scoop-and-level method will differ from one measured by the spoon-and-level method by as much as 30 grams — enough to noticeably affect the texture of your baked goods.
Use the swap button between the from and to fields to quickly reverse a conversion. This is handy when a recipe lists grams and you want to know the equivalent in cups, or when you need to convert back and forth while adapting a recipe. All conversions in this tool use standard US cup measurements (240 ml) and widely accepted ingredient density values sourced from authoritative references including the USDA and leading baking authorities.
Frequently Asked Questions
Why does 1 cup of flour weigh differently than 1 cup of sugar?
Cups measure volume, not weight. Different ingredients have different densities. One cup of all-purpose flour weighs about 125 grams, while one cup of granulated sugar weighs about 200 grams. This is because sugar granules pack more tightly than flour particles. For accurate baking, always convert cups to grams using ingredient-specific densities.
How many grams are in a cup?
The number of grams in a cup depends entirely on the ingredient. For water, 1 cup equals approximately 240 grams. For all-purpose flour, 1 cup is about 125 grams. For butter, 1 cup is about 227 grams. For granulated sugar, 1 cup is about 200 grams. Always use an ingredient-specific converter for accurate results.
What is the difference between a US cup and a metric cup?
A US customary cup equals 236.588 ml (commonly rounded to 240 ml), while a metric cup used in Australia and some other countries equals exactly 250 ml. A US legal cup, used in nutrition labeling, equals exactly 240 ml. This converter uses the US customary cup (240 ml), which is the most common standard in recipes.
How many cups of flour are in a pound?
One pound (454 grams) of all-purpose flour equals approximately 3.6 cups when measured using the spoon-and-level method. For bread flour, it is about 3.5 cups per pound because bread flour is slightly denser. For cake flour, which is lighter, one pound is approximately 4 cups. These values vary depending on how you scoop the flour, which is why weighing in grams is always more reliable than measuring by volume.
How many tablespoons are in a cup?
There are exactly 16 tablespoons in 1 US cup. This means 1 tablespoon equals 1/16 of a cup, or 0.0625 cups. For quick kitchen reference: 4 tablespoons equal 1/4 cup, 8 tablespoons equal 1/2 cup, and 12 tablespoons equal 3/4 cup. Each tablespoon contains 3 teaspoons, so 1 cup also equals 48 teaspoons.
How many grams of butter are in a stick?
One standard US stick of butter weighs exactly 113 grams (4 ounces). A stick is also equal to 1/2 cup or 8 tablespoons. Two sticks equal one cup (227 grams), and four sticks make one pound (454 grams). Butter is one of the easiest ingredients to measure because the wrapper is marked with tablespoon lines, but using grams from a scale is still the most precise approach for baking.
