You're halfway through a recipe, and it asks for 80 grams of something but your kitchen only has cups. The good news: converting 80 grams to cups is simple once you know the one variable that changes everything, the ingredient's density.
Use the calculator above for an instant answer across more than 50 ingredients. Below, you'll find a full breakdown by ingredient, dry vs. liquid comparisons, and the exact formula behind every number on this page.
How Many Cups Is 80 Grams? (Quick Answer)
Here's how 80 grams converts to cups for the most commonly searched ingredients:
| Ingredient | 80g in Cups |
| All-Purpose Flour | 0.67 cups (2/3 cup) |
| Cake Flour | 0.70 cups |
| Granulated Sugar | 0.40 cups |
| Caster Sugar | 0.40 cups |
| Brown Sugar (Packed) | 0.36 cups |
| Butter | 0.35 cups |
| Cocoa Powder | 0.80 cups |
| Chocolate Chips | 0.50 cups |
| Cornstarch | 0.67 cups |
| Rice (Uncooked) | 0.43 cups |
| Rice (Cooked) | 0.46 cups |
| Water | 0.34 cups |
| Milk | 0.34 cups |
| Greek Yogurt | 0.33 cups |
| Blueberries | 0.54 cups |
| Cheese (Shredded) | 0.71 cups |
| Coffee (Ground) | 0.80 cups |
Notice cocoa powder and coffee grounds fill nearly a full cup, while butter barely reaches a third. Same weight, wildly different volumes that's density at work.
80 Grams to Cups by Ingredient
80 Grams of Flour to Cups
80 grams of all-purpose flour equals about 0.67 cups, or 2/3 cup, based on the standard spoon-and-level measurement of 120 grams per cup. Cake flour is lighter and airier, so 80 grams of it measures slightly more about 0.70 cups.
80 Grams of Sugar to Cups
80 grams of granulated sugar equals 0.40 cups. Caster sugar (also called superfine sugar) has essentially the same density as granulated sugar, so the conversion is the same. Brown sugar, packed firmly, is denser at 220 grams per cup, so 80 grams of it works out to a smaller 0.36 cups.
80 Grams of Butter to Cups
80 grams of butter equals about 0.35 cups, roughly 1/3 cup plus a couple of teaspoons. Since butter is a solid block rather than loose granules, this is one of the more reliable conversions on this page.
80 Grams of Cocoa Powder to Cups
80 grams of cocoa (or cocoa powder) equals 0.80 cups, close to a full cup. Cocoa is fine and light, so it takes up far more space per gram than denser ingredients like sugar or flour.
80 Grams of Cornstarch to Cups
80 grams of cornstarch equals about 0.67 cups, the same ratio as all-purpose flour, since the two have very similar densities.
80 Grams of Rice to Cups (Cooked and Uncooked)
80 grams of uncooked rice equals about 0.43 cups. Once cooked, rice absorbs water and becomes less dense per gram in some cooking styles, so 80 grams of cooked rice measures slightly more, around 0.46 cups. This is one ingredient where checking whether your recipe means cooked or uncooked really matters the volume needed is very different for the same starting weight.
80 Grams of Water to Cups
80 grams of water equals 0.34 cups. Water is the reference point most conversion charts are built around, since 1 milliliter of water weighs almost exactly 1 gram.
80 Grams to Cups: Milk
80 grams of milk equals about 0.34 cups, nearly identical to water, since milk is over 85% water by weight.
80 Grams of Greek Yogurt to Cups
80 grams of Greek yogurt equals about 0.33 cups. Greek yogurt is strained and slightly thicker than regular yogurt, which makes it marginally denser per cup.
80 Grams of Blueberries to Cups
80 grams of blueberries equals about 0.54 cups. Whole berries leave gaps of air between them in a measuring cup, so this conversion can shift depending on berry size smaller berries pack more tightly than larger ones.
80 Grams of Cheese to Cups
80 grams of shredded cheese (like cheddar) equals about 0.71 cups. Cheese density varies a lot by type and how finely it's shredded or grated finely grated hard cheeses like Parmesan pack more densely than coarsely shredded soft cheeses.
80 Grams of Coffee to Cups
80 grams of ground coffee equals about 0.80 cups. Whole coffee beans are denser and take up less room, so the same weight of whole beans measures noticeably less than ground coffee.
Dry vs. Liquid: Does 80 Grams Convert Differently?
80 grams to cups (liquid): Liquids like water, milk, and oil convert predictably, since they fill a cup evenly with no air gaps. 80 grams of water and 80 grams of milk both land close to 0.34 cups.
80 grams to cups (dry): Dry ingredients vary far more, because how they're packed changes the final volume. 80 grams of cocoa powder (0.80 cups) takes up more than double the space of 80 grams of butter (0.35 cups) both are "dry" measurements in the sense of not being poured liquids, but their densities are worlds apart.
This is why a single "80 grams = X cups" rule never works across the board you always have to check the specific ingredient.
Why Does 80 Grams Fill a Different Amount of Every Cup?
The answer is density how tightly an ingredient's particles pack together.
- Cocoa powder and coffee grounds are fine and light, trapping lots of air, so 80 grams fills close to a full cup.
- Butter and cream cheese are dense and uniform, so 80 grams fills only about a third of a cup.
- Flour and cornstarch sit in between, both around 0.67 cups for 80 grams.
How to Convert 80 Grams to Cups (Formula)
Cups = Grams ÷ Grams-Per-Cup Value
Worked Example: 80 Grams of Flour
- Find the grams-per-cup value for flour: 120 grams.
- Divide: 80 ÷ 120 = 0.667.
- Round to 2 decimal places: 0.67 cups.
Swap in any ingredient's grams-per-cup value, and the same formula applies every time.
Common Questions About 80 Grams
Is 80 grams equal to how many cups exactly? There's no single exact answer it always depends on the ingredient. The range for common baking ingredients runs from about 0.33 cups (Greek yogurt) to 0.80 cups (cocoa powder).
Is 80 grams about 1/3 cup? For dense ingredients like butter or cream cheese, yes 80 grams is close to 1/3 cup. For lighter ingredients like flour or cocoa powder, 80 grams is noticeably more than 1/3 cup.
80 grams to oz how does that compare to cups? 80 grams is about 2.82 ounces by weight. This is a separate conversion from cups, since ounces here measure weight, not fluid volume don't confuse a weight-ounce with a fluid-ounce measuring cup marking.

How many cups is 80 grams of sugar?
80 grams of granulated sugar is about 0.40 cups, based on 200 grams per cup. Caster sugar converts the same way, since the two have very similar densities.
Is 80 grams the same in cups for dry and liquid ingredients?
No. Liquids like water and milk convert predictably to about 0.34 cups, but dry ingredients vary widely cocoa powder fills 0.80 cups at the same weight, while butter fills only about 0.35 cups.
What's the most accurate way to measure 80 grams?
A digital kitchen scale is the most accurate method, since it removes guesswork entirely. If you don't have one, use the ingredient-specific chart on this page, which is based on standard spoon-and-level measurements.

Final Thoughts
Converting 80 grams to cups always comes down to the same principle: grams measure weight, cups measure volume, and an ingredient's density is what connects the two. Whether you're working with flour, sugar, cocoa powder, or cheese, checking the specific ingredient rather than assuming one number applies everywhere is what makes the difference between a rough guess and an accurate measurement.
