How to Convert Cups to Grams for Baking
Converting cups to grams requires knowing the ingredient's density because different ingredients have different weights per cup. For example, 1 cup of all-purpose flour weighs 125g, while 1 cup of granulated sugar weighs 200g. Our calculator uses precise density values for accurate conversions.
Step 1: Select Ingredient
Choose your ingredient from 20+ options. Each has a unique gram-per-cup conversion rate.
Step 2: Enter Amount
Input how many cups you need to convert. Works with decimals like 0.5 or 1.75 cups.
Step 3: Get Grams
Instantly see the exact gram measurement for precise baking.
Understanding Cup Sizes for Gram Conversions
Not all cups are created equal! Cup measurements vary significantly by region, which directly affects your gram conversions. Using the wrong cup size can throw off your entire recipe.
| Cup Type | Volume | Flour Weight | Sugar Weight |
|---|---|---|---|
| US Customary | 237 mL | 125g | 200g |
| Metric | 250 mL | 132g | 211g |
| Imperial (UK Old) | 284 mL | 150g | 240g |
Important: Most American recipes use US Customary cups (237 mL), while UK/Australian recipes often use Metric cups (250 mL). Always check your recipe's origin to ensure accurate conversions!
Why Accurate Cup to Gram Conversions Matter
Converting cups to grams is essential for baking success. Volume measurements (cups) can vary by 20-30% depending on how you scoop and pack ingredients, while weight measurements (grams) are always consistent. This is why professional bakers always weigh their ingredients.
The Flour Problem
One cup of flour can weigh anywhere from 110g to 145g depending on measuring method. This 35g difference can turn a perfect cake into a dry, dense disaster.
The Scale Solution
A digital kitchen scale costs under $20 and ensures perfect results every time. Use our converter to translate cup-based recipes into precise weight measurements.
Common Cup to Gram Conversion Mistakes
❌ Mistake 1: Scooping Flour Directly
Scooping flour with the measuring cup compacts it, adding 30% more flour than intended.
✓ Solution: Spoon flour into the cup and level off with a knife, or better yet, weigh it.
❌ Mistake 2: Assuming All Cups Are the Same
Using a UK recipe with US measuring cups (or vice versa) changes ingredient amounts by 5-20%.
✓ Solution: Check recipe origin and use our cup size selector for accurate conversions.
❌ Mistake 3: Using One Conversion for All Ingredients
1 cup does NOT equal 240g for everything! Flour is 125g, sugar is 200g, butter is 227g per cup.
✓ Solution: Always select the specific ingredient in our converter for accurate results.
Frequently Asked Questions
One US cup of all-purpose flour weighs 125 grams when measured using the spoon-and-level method. Bread flour is slightly heavier at 130g per cup, while cake flour is lighter at 115g per cup. The type of flour and measuring technique significantly impact the weight.
One US cup of granulated white sugar weighs 200 grams. Brown sugar (packed) is 220g per cup, and powdered sugar is only 120g per cup. Always specify which type of sugar when converting for accurate results.
Each ingredient has a unique density. Cups measure volume (the space something takes up), while grams measure mass (actual weight). Dense ingredients like sugar pack more mass into a cup than airy ingredients like flour. This is why you need ingredient-specific conversions for accuracy.
Yes! Our calculator handles any cup amount including fractions. For example, 1/2 cup flour = 62.5g, 1/3 cup flour = 41.7g, and 1/4 cup flour = 31.3g. Just enter the decimal equivalent (0.5, 0.33, 0.25) or use our preset buttons for common fractions.
If a recipe says "1 cup flour, sifted," weigh first then sift. If it says "1 cup sifted flour," sift first then weigh. This distinction matters because sifting increases volume by adding air, so sifted flour weighs less per cup (about 100g vs 125g for all-purpose flour).
