How Cups to Grams Conversion Works
Unlike liquid measurements, the weight of dry ingredients per cup varies significantly depending on the ingredient. One cup of flour weighs much less than one cup of sugar, because flour is less dense.
Why weight matters for baking: Measuring by weight (grams) is more accurate than measuring by volume (cups). The same cup of flour can weigh anywhere from 120g to 160g depending on how tightly it is packed. This variability is one of the main reasons baked goods fail.
Common conversions:
All-Purpose Flour: 1 cup = 125g | Granulated Sugar: 1 cup = 200g | Brown Sugar (packed): 1 cup = 220g | Butter: 1 cup = 227g | Water/Milk: 1 cup = 240g (approximately)
For best results when baking, use a kitchen scale and measure ingredients by weight rather than volume.
The cup is a volume measurement used primarily in American cooking, while the gram is a weight measurement used in professional kitchens and throughout most of the world. One US cup equals 236.588 milliliters, but the weight in grams depends entirely on what you are measuring: a cup of flour weighs about 125 grams, while a cup of sugar weighs about 200 grams, and a cup of butter weighs about 227 grams. This variability is why professional bakers and international recipes strongly prefer weight measurements in grams. Converting cups to grams for specific ingredients eliminates the inconsistency of volume-based measuring, where how you scoop, pack, or level the ingredient significantly affects the amount. This converter provides accurate cup-to-gram values for the most common cooking and baking ingredients.
How to Convert Cups to Grams
Since the conversion depends on the ingredient's density, there is no single formula. Here are the steps:
Identify the ingredient
Look up or calculate its grams-per-cup value
Multiply: grams = cups × grams-per-cup
Worked example: A recipe calls for 2.5 cups of all-purpose flour.
All-purpose flour: 1 cup = 125 g
2.5 × 125 = 312.5 grams
Tip: For water and other thin liquids, 1 cup = 237 mL = approximately 237 grams, since water has a density close to 1 g/mL.

Frequently Asked Questions
Why does 1 cup of flour weigh less than 1 cup of sugar?
Flour is less dense than sugar. Flour granules are irregularly shaped and trap air, giving it a lower weight per volume. Sugar granules are more uniform and pack more tightly. This is exactly why weight-based measurements (grams) are more reliable than volume-based measurements (cups) for baking.
Is 1 cup always 8 ounces?
One cup is 8 fluid ounces by volume, but the weight in ounces depends on the ingredient. A cup of water weighs about 8.35 oz, a cup of flour about 4.4 oz, and a cup of honey about 12 oz. Fluid ounces measure volume; regular ounces measure weight.
How do I measure a cup of flour correctly?
For consistent results: use the spoon-and-level method. Stir the flour to aerate it, spoon it into the measuring cup until it overflows, then level off the top with a straight edge. Do not scoop directly from the bag, as this can pack the flour and give you up to 30% more than intended.
What is the difference between US cups and metric cups?
A US cup is 236.588 mL, while a metric cup (used in Australia and some other countries) is exactly 250 mL. The difference is about 5.7%, which can matter in precision baking. UK recipes sometimes use imperial cups (284 mL), which are larger still.
Can I convert any recipe from cups to grams?
Yes, and it is recommended for consistent results. Measure each ingredient in your recipe once using cups and a kitchen scale simultaneously to build a personal reference. Alternatively, use a reliable conversion chart like the one above. Most professional baking resources provide gram measurements.
How many tablespoons in a cup?
There are 16 tablespoons in 1 US cup, and 3 teaspoons in 1 tablespoon. So 1 cup = 48 teaspoons. For quick reference: 1/4 cup = 4 tablespoons, 1/3 cup = 5 tablespoons + 1 teaspoon, 1/2 cup = 8 tablespoons.

Cups to Grams Converter - Cooking Measurement Calculator across industries
Unit conversions are critical in international trade, science, engineering, healthcare, cooking, and travel. Scientists worldwide use the metric system, but many countries (notably the US) still use imperial units in daily life, creating a constant need for conversion. In engineering and manufacturing, incorrect unit conversions have caused spectacular failures — NASA lost the $125 million Mars Climate Orbiter in 1999 because one team used metric units while another used imperial. In healthcare, medication dosages must be converted accurately between units — a mistake can be life-threatening. International shipping requires conversions between pounds and kilograms, miles and kilometers, gallons and liters. Even cooking recipes often need conversion when following recipes from different countries. This converter handles all the common cups to grams - cooking measurement scenarios with precision.
