50 Grams to Cups
50g is about 0.42 US cups of all-purpose flour, 0.25 cups of granulated sugar or 0.22 cups of butter.
Choose the ingredient first: the same weight does not fill the same fraction of a cup for every food.
50 grams to cups by ingredient
This chart uses the site's US Customary cup setting, 236.588mL. Answers are approximate and rounded to a maximum of two decimal places, with unnecessary trailing zeros removed.
| Ingredient | 50g in US cups, approximately | Preparation or type |
|---|---|---|
| All-purpose flour | 0.42 | Fluffed, spooned and leveled |
| Granulated white sugar | 0.25 | Dry granulated sugar |
| Butter | 0.22 | Standard butter, not whipped |
| Brown sugar | 0.23 | Packed, light or dark |
| Powdered sugar | 0.44 | Unsifted |
| Rolled oats | 0.56 | Dry old-fashioned oats |
| White rice | 0.27 | Raw, regular long-grain white rice |
| Honey | 0.15 | Strained or extracted honey |
| Olive oil | 0.23 | Olive oil, not every cooking oil |
| Whole milk | 0.2 | Fluid whole milk; reference entry is 3.3% fat |

Is 50g a quarter cup or half a cup?
It depends on the ingredient. Under our references, ¼ cup of granulated sugar is 49.5g, so it is close to 50g. But ¼ cup of flour is only 30g, and ½ cup is 60g.
The sugar row displays 0.25 cups because the full result, about 0.2525 cups, rounds to two decimals. That rounded answer does not make 50g exactly equal to a quarter cup.
When a recipe gives 50g and you have a scale, weigh 50g directly. When you need a cup estimate, use the row matching your ingredient rather than assuming one fraction works for everything.
How can I measure 50g without a scale?
For all-purpose flour, our US Customary reference gives ¼ cup + 2 tablespoons + 2 teaspoons. Spoon the flour into the measures and level it without packing. Our flour-measuring guide explains the method.
This combination represents 50g under our reference, but the amount you actually scoop can vary. It also uses US customary spoons; do not mix it with a different spoon standard. For another ingredient, let the calculator generate its own measuring suggestion.
Check the preparation too: brown sugar is packed, powdered sugar is unsifted, and the rice and oats in the chart are uncooked. The ingredient links above explain each reference in more detail.
How the 50g conversion is calculated
Divide 50 by the ingredient's reference weight per cup:
Cups = 50 ÷ grams per cup
For example, flour uses 120g per cup, so 50 ÷ 120 = about 0.42 cups. Butter uses 227g per cup, so 50 ÷ 227 = about 0.22 cups.
These references come from King Arthur Baking, Land O'Lakes and the USDA's Nutritive Value of Foods, revised in 2002. The grams-per-cup chart identifies the source and scope for each ingredient.
If your recipe gives its own gram equivalent, follow that reference. A different product or measuring method can produce a different cup weight.
What if my measuring cup is 250mL?
Select Metric in the calculator. This page's table stays on the US Customary setting. Under our proportional scaling method, 50g of all-purpose flour is about 0.39 metric cups, compared with 0.42 US Customary cups.
Check our cup-size guide for the standards and spoon differences. Our methodology explains how the estimates are calculated and rounded.
