Grams to Cups Conversion Chart & Easy Calculator
Converting grams to cups is not always as simple as using one number. Grams measure weight, while cups measure volume. That means 100 grams of flour does not fill the same number of cups as 100 grams of sugar, butter, oats, rice, or honey.
This grams to cups conversion chart gives you quick ingredient-based reference values, while the calculator below lets you choose the exact ingredient and cup standard you need.
Cups = Grams ÷ Grams per Cup. For example, our all-purpose flour reference is 125g per US cup, so 100g ÷ 125g = 0.80 cup.

How to Convert Grams to Cups
Cups = Grams ÷ Grams per Cup
For all-purpose flour:
250 ÷ 125 = 2 cups
For granulated sugar:
250 ÷ 200 = 1.25 cups
This is why one general grams-to-cups number cannot work for every ingredient.
For a deeper explanation of the method, cup-size adjustment, and reverse formula, read How We Calculate Grams to Cups.
Why Ingredient Density Matters
Density tells us how much weight fits into a certain amount of space. Flour is light, granulated sugar is heavier, butter is denser, and honey is heavier still. So the same weight can produce very different cup measurements.
| Ingredient | Approx. Weight per US Cup | 100g in Cups |
|---|---|---|
| All-Purpose Flour | 125g | 0.80 cup |
| Granulated Sugar | 200g | 0.50 cup |
| Brown Sugar, Packed | 213g | 0.47 cup |
| Butter | 227g | 0.44 cup |
| Water | 236.6g | 0.42 cup |
| Rolled Oats | 90g | 1.11 cups |

Tips for More Accurate Conversions
Use a Kitchen Scale
A scale measures grams directly and is especially useful when a baking recipe gives weight measurements.
Do Not Pack Flour
Spoon flour lightly into the measuring cup and level it unless your recipe says otherwise.
Pack Brown Sugar When Required
If the recipe says “packed brown sugar,” press it into the cup before leveling.
Check Ingredient Form
Whole, chopped, sifted, melted, and packed versions of the same food can have different weights per cup.
Trusted Measurement References
NIST Metric Kitchen
NIST provides household cooking measurement equivalencies and culinary measurement guidance.
View NIST measurement equivalencies →King Arthur Ingredient Weight Chart
King Arthur Baking publishes a searchable chart of volume and gram values for many baking ingredients.
View ingredient weight chart →Different culinary references may use slightly different grams-per-cup values. For consistency across this site, our calculator and grams to cups conversion chart use one fixed internal ingredient database.
Should You Measure in Grams or Cups?
Both can work. Cups are convenient for everyday cooking, while grams are often easier when precision matters. A kitchen scale measures weight directly, so the result is less affected by how tightly an ingredient is packed into a cup.
Frequently Asked Questions
How do I convert grams to cups?
Divide the number of grams by the grams-per-cup value for the ingredient. For example, 125g ÷ 125g per cup = 1 cup of all-purpose flour in our reference system.
How many cups is 100 grams?
It depends on the ingredient. 100g of all-purpose flour is about 0.80 cup, while 100g of granulated sugar is about 0.50 cup.
Is there one grams to cups conversion for every ingredient?
No. Different foods have different densities, so their grams-per-cup values are different.
How many grams are in one cup of flour?
Our converter uses 125 grams per US cup for all-purpose flour.
How many grams are in one cup of sugar?
Our converter uses 200 grams per US cup for granulated sugar.
Does cup size change the conversion?
Yes. US customary, US legal, metric, and Imperial cups have different volumes, so the result can change when the cup standard changes.
Is this grams to cups conversion chart exact?
It is a practical kitchen reference. Small differences can happen because of brand, moisture, packing, ingredient form, and measuring technique.
