100 Grams to Cups: Conversion Chart & Calculator
Need to convert 100 grams to cups? There is no single cup answer for every food because grams measure weight while cups measure volume. For example, 100 grams of all-purpose flour is about 0.80 US cup, while 100 grams of granulated sugar is 0.50 cup.
Use the quick answers below for common ingredients, then use the preset calculator or full chart when you need a more specific 100g to cups conversion.
100 grams of all-purpose flour = 0.80 US cup, which is about ¾ cup as a practical kitchen fraction. For granulated sugar, 100 grams is ½ cup. Butter, oats, rice, honey, and other ingredients give different results.

Preset to 100 grams — choose your ingredient for an instant cups conversion.
100g ÷ 125g per cup = 0.8 cups
Why ingredient matters: grams measure weight while cups measure volume. Different ingredients have different densities, so 100 grams of flour does not equal the same number of cups as 100 grams of sugar or butter.

How Many Cups Is 100 Grams?
100 grams is not one fixed number of cups. The answer depends on the ingredient. A light ingredient such as oats takes up more cup space than a dense ingredient such as honey.
For quick reference, 100 grams is about 0.80 cup of all-purpose flour, 0.50 cup of granulated sugar, 0.44 cup of butter, and 1.11 cups of rolled oats.
How to Convert 100 Grams to Cups
To convert 100 grams to cups, divide 100 by the grams-per-cup value for the ingredient you are measuring.
For all-purpose flour, our site-wide reference is 125 grams per US cup.
100 ÷ 125 = 0.80 cupSo 100 grams of all-purpose flour is about 0.80 US cup.

100 Grams to Cups for Popular Ingredients
These are the ingredient conversions people most often need when a recipe gives 100g but their measuring tools use cups.
100g Flour to Cups
100 grams of all-purpose flour is about 0.80 cup. A practical kitchen fraction is about ¾ cup, though a scale is more precise.
100g Sugar to Cups
100 grams of granulated sugar is 0.50 cup, or exactly ½ cup using our 200g-per-cup reference.
100g Butter to Cups
100 grams of butter is about 0.44 cup, which is close to ½ cup.
100g Oats to Cups
100 grams of rolled oats is about 1.11 cups, close to 1⅛ cups.
100g Rice to Cups
100 grams of uncooked white rice is about 0.54 cup. Cooked rice should use a different value.
100g Honey to Cups
100 grams of honey is about 0.29 cup, a little more than ¼ cup.
100g Cocoa Powder to Cups
100 grams of cocoa powder is about 1.18 cups using the value in our converter.
100g Milk to Cups
100 grams of milk is about 0.41 cup, which is close to ⅜ cup.
Is 100 Grams Equal to 1 Cup?
Sometimes it can be close, but 100 grams does not automatically equal 1 cup. For example, 100 grams of almond flour is just over 1 cup in our database, while 100 grams of sugar is only ½ cup and 100 grams of honey is less than ⅓ cup.
This is why a generic “100g = 1 cup” rule can give the wrong result. Choose the ingredient first.
Why 100 Grams Changes by Ingredient
Grams measure weight, while cups measure volume. Flour contains more air between particles. Sugar packs more tightly. Honey is dense and heavy. Oats are light and bulky.
The same 100-gram weight therefore occupies a different amount of cup space for each ingredient.
100 Grams in Cups, Tablespoons, and Teaspoons
If the cup value is awkward, tablespoons or teaspoons can be easier for small adjustments. Our calculator automatically shows cups, a kitchen fraction, tablespoons, and teaspoons for the selected ingredient.
For example, 100 grams of all-purpose flour is about 12.8 US tablespoons, while 100 grams of granulated sugar is about 8 tablespoons.
US Cup, Metric Cup, and Other Cup Sizes
The chart above uses a US customary cup. Recipes can use different cup standards, so the same ingredient weight may convert to a slightly different cup reading.
| Cup Standard | Volume | Common Use |
|---|---|---|
| US Customary Cup | 236.6 ml | Common US recipes |
| US Legal Cup | 240 ml | US labeling references |
| Metric Cup | 250 ml | Many metric recipes |
| Imperial Cup | 284.1 ml | Older Imperial references |
Trusted Measurement References
For household volume and mass equivalencies, see the NIST Metric Kitchen measurement guide. For published ingredient weight comparisons, see the King Arthur Baking ingredient weight chart.
Published charts can use different grams-per-cup values because brands, methods, and ingredient condition vary. Our calculator uses one consistent internal database so the results on our amount pages match each other.How to Measure 100 Grams Accurately
If a recipe gives 100 grams, a digital kitchen scale is the easiest and most consistent option. Place the bowl on the scale, press tare, then add the ingredient until the display reaches 100g.
If you need cups instead, measure the ingredient as the recipe expects. Spoon and level flour rather than packing it. Pack brown sugar only when instructed, and check whether an ingredient is chopped, sifted, melted, or uncooked before using a conversion.
