400 grams equals 3.33 cups (3 1/3 cups) of flour, exactly 2.0 cups of granulated sugar, and 1.76 cups of butter.
Adjust ingredients below to calculate the exact volume for 400g.
Technique note: Fluff flour with a fork, spoon gently into the cup until heaping, then sweep level with a straight edge. Never scoop directly.
Verified standard: 1 US cup of All-Purpose Flour = 120 grams (King Arthur Baking & USDA FoodData Central (FDC ID: 168936)).
Below is the exact conversion of 400g into US Customary cups and level tablespoons for common baking staples:
| Ingredient | US Cups | Tablespoons | Measuring Notes |
|---|---|---|---|
| Granulated Sugar | 2.00 cups (Exact 2 cups) | 32.0 tbsp | Exact 2 full cups |
| All-Purpose Flour | 3.33 cups (3 1/3 cups) | 53.3 tbsp | Spooned and leveled |
| Brown Sugar (Packed) | 1.82 cups (1 3/4 cups + 1 tbsp) | 29.1 tbsp | Packed firmly |
| Butter | 1.76 cups (1 3/4 cups) | 28.2 tbsp | 3.5 sticks of butter |
| Powdered Sugar | 3.33 cups (3 1/3 cups) | 53.3 tbsp | Sifted confectioners |
| White Rice (Uncooked) | 2.16 cups (2 1/8 cups) | 34.6 tbsp | Grains |
400 grams is double the standard sugar benchmark, representing exactly 2.0 cups of granulated white sugar.
Culinary Tip: For light powders like flour and cocoa, always fluff the ingredient before spooning it into the cup, then scrape the top level with a flat straight edge. For packed ingredients like brown sugar, press firmly with a spoon.
