Grams to Cups Converter
Convert grams to cups accurately for flour, sugar, butter and other cooking ingredients. Select an ingredient and instantly calculate grams-to-cups conversions.
100 grams All-Purpose Flour
0.83cups
Note: All-Purpose Flour weighs about 120 g per US cup. Flour weight can vary by ±10% or more depending on measurement method, brand, compaction, and humidity. For baking precision, weighing is more reliable than measuring by volume.How to measure: Spoon flour into the cup and level off with a straight edge. Do not scoop.

Conversion Summary
How it works
Grams measure mass and cups measure volume, so there is no single grams-to-cups conversion. Each ingredient has a different density — 100 g of flour is about 0.83 cups, while 100 g of sugar is about 0.5 cups. Select your ingredient above and Cookometry will use the correct weight reference to convert grams to cups.

How to Convert Grams to Cups
Grams measure weight (mass), while cups measure volume. To convert between them you need the ingredient's density — how much a cup of that ingredient weighs.
The formula is simple:
cups = grams ÷ grams per cup
For example, if one cup of all-purpose flour weighs 120 grams:
- 120 g ÷ 120 g per cup = 1 cup
- 60 g ÷ 120 g per cup = 0.5 cup
- 30 g ÷ 120 g per cup = 0.25 cup
Select your ingredient in the calculator above and Cookometry applies the correct weight reference automatically.

Why Grams Don't Convert Directly to Cups
A gram is a measure of mass, while a cup is a measure of volume. There is no single universal conversion between them because every ingredient has a different density.
For example, 100 grams of all-purpose flour fills about 0.83 cups, while 100 grams of granulated sugar fills only 0.5 cups. The same weight occupies a very different volume depending on what you're measuring.
That's why Cookometry always asks you to select an ingredient before converting grams to cups — the correct answer depends on what you're weighing.
Grams vs Cups
A gram is a metric unit of mass used worldwide. It measures how heavy an ingredient is, regardless of how much space it takes up.
A cup is a unit of volume — it measures how much space an ingredient fills. Because ingredients pack differently, a cup of one ingredient can weigh far more or less than a cup of another.
For baking, a digital kitchen scale that reads in grams is generally more precise than measuring cups, because it eliminates the variation caused by scooping, spooning, and packing.
Why Ingredient Weight Matters in Baking
Baking is more sensitive to small measurement differences than everyday cooking. Ingredients like flour can vary by 20% or more depending on whether you scoop it from the bag, spoon it into the cup, or sift it first. That variation is enough to change the texture of a cake, cookie, or loaf of bread. Weighing ingredients in grams removes that guesswork and gives you the same result every time. If a recipe gives weights, use them — and if it doesn't, Cookometry helps you convert cup measurements to grams so you can weigh for consistency.
