How Much Is 100 Grams in Cups?
100 grams of all-purpose flour is about ¾ cup. That number changes with the ingredient, because grams measure weight while cups measure volume. The table below shows 100g converted for 20 ingredients people search for most.

Why the Cup Value Changes by Ingredient
100g of flour and 100g of honey have identical mass, but flour is airy while honey is thick and heavy. That difference in density, not the weight itself, decides how much space each one takes up in a cup. A cup is a fixed volume, so a lighter ingredient needs more of it to reach the same weight, and a heavier ingredient needs less.
This is also why a single all-purpose grams to cups converter can't use one shared number for every ingredient. Each row in the table above is calculated from that ingredient's own density, sourced from USDA FoodData Central where available.
Granulated Sugar
100g ≈ ½ cup
Butter
100g ≈ ½ cup
Honey
100g ≈ ⅓ cup
All-Purpose Flour
100g ≈ ¾ cup
How This Conversion Is Calculated
Every value on this page comes from that formula. For all-purpose flour, 125g fills one US cup, so 100g of flour divided by 125 gives 0.80 cups. Tablespoon and teaspoon figures scale from the cup result: 1 cup equals 16 tablespoons and 48 teaspoons, so multiplying the cup value by those factors gives the spoon measurements shown in the converter above.
Sifted: 115g. Scooped and packed: up to 150g. Recipes that specify sifted or packed flour will land on a different cup value even at the same 100g, since sifting and packing change how much air sits between the particles.
US, Metric, and Imperial Cups at 100g
Not every "cup" holds the same volume. A US customary cup is 236.588ml, a metric cup is 250ml, and an imperial (UK) cup is 284.131ml. That difference shifts the cup count even when the gram amount and the ingredient stay the same.
100g of all-purpose flour: ¾ US Customary cups, ¾ Metric cups, ⅔ Imperial (UK) cups.
Use the cup standard switch in the converter above if your recipe was written outside the US.
Measuring 100g Without a Scale
Most accurate
A kitchen scale reads 100g directly and removes scooping error entirely.
Dry ingredients
Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.
Liquids
Pour into a liquid measuring cup and read the line at eye level, not from above.
Packed ingredients
Brown sugar and similar ingredients should be pressed firmly if a recipe calls for a packed cup.

Frequently Asked Questions
How much is 100 grams in cups?+
It depends on the ingredient. For all-purpose flour, 100g is about 0.80 cups. Check the table above for other common ingredients.
Is 100 grams the same in cups for every ingredient?+
No. Cups measure volume and grams measure weight, so the cup value changes based on how dense the ingredient is.
What's a quick way to measure 100 grams without a scale?+
Use the fraction cup value shown for your specific ingredient in the table above, measured with a spoon-and-level dry cup.
Is 100 grams the same as 100 milliliters?+
Close only for water. 100g of water is about 100ml, since water's density is close to 1g per milliliter. Other ingredients weigh differently per milliliter.
