Grams to Cups Converter
Converting weight in grams back to volume in cups can be confusing, especially when baking international recipes. Since grams measure weight and cups measure volume, the conversion depends entirely on the density of your ingredient.
Our free Grams to Cups Calculator takes away the math stress. Simply select your ingredient, type in the weight in grams, and get instant, accurate cup conversions optimized for US, UK, and Australian cup sizes. Going the other way instead? Use our cups to grams Converter.

What Is a Grams to Cups Converter?
A Grams to Cups Converter is a specialized culinary tool that translates dry or liquid weights (grams) into practical kitchen measuring cups.
Because lighter ingredients like flour occupy more physical space than dense ingredients like granulated sugar or butter, 100 grams of flour will fill much more of a cup than 100 grams of sugar. This converter automatically adjusts for these ingredient densities, ensuring your baking turns out light, fluffy, and perfectly balanced every time.

The Grams to Cups Formula
To convert grams to cups for an ingredient, you need three things:
- The cup size (a US cup is 236.59ml)
- The ingredient's density (in g/cm³ or g/ml)
- The weight in grams
The easiest way to use this is with the calculator above, which handles the maths for you. As an example, the calculation for 100g of all-purpose flour works out as: 100g ÷ (236.59ml × 0.529 g/ml) = 100 ÷ 125 ≈ 0.8 cups.
These figures are close approximations based on standard ingredient densities. Actual results can vary slightly depending on brand, temperature, and whether the cup was spooned-and-levelled or scooped-and-packed.
Grams to Cups for Flour
Flour is one of the most common ingredients that causes baking mistakes due to packing. Below is a quick conversion reference for all-purpose flour from grams to standard cups.
| Grams of Flour | Cups (US) | Approx. Fraction |
|---|---|---|
| 10 g | 0.08 cups | less than 1/4 cup |
| 20 g | 0.16 cups | ~1/4 cup |
| 30 g | 0.24 cups | 1/4 cup |
| 40 g | 0.32 cups | ~1/3 cup |
| 50 g | 0.4 cups | ~1/3 cup |
| 100 g | 0.8 cups | ~3/4 cup |
| 150 g | 1.2 cups | ~1 and 1/4 cups |
| 200 g | 1.6 cups | ~1 and 2/3 cups |
| 250 g | 2 cups | 2 cups |
| 300 g | 2.4 cups | ~2 and 1/3 cups |
| 350 g | 2.8 cups | ~2 and 3/4 cups |
| 400 g | 3.2 cups | ~3 and 1/4 cups |
| 450 g | 3.6 cups | ~3 and 2/3 cups |
| 500 g | 4 cups | 4 cups |
Note: conversions are for US cups (236.6ml) and all-purpose flour.
Grams to Cups for Sugar
Granulated white sugar is heavier and denser than flour, meaning fewer cups are needed for the same gram weight. Use the table below for quick reference.
| Grams of Sugar | Cups (US) | Approx. Fraction |
|---|---|---|
| 10 g | 0.05 cups | less than 1/4 cup |
| 20 g | 0.1 cups | less than 1/4 cup |
| 30 g | 0.15 cups | less than 1/4 cup |
| 40 g | 0.2 cups | ~1/4 cup |
| 50 g | 0.25 cups | 1/4 cup |
| 100 g | 0.5 cups | 1/2 cup |
| 150 g | 0.75 cups | 3/4 cup |
| 200 g | 1 cup | 1 cup |
| 250 g | 1.24 cups | ~1 and 1/4 cups |
| 300 g | 1.49 cups | ~1 and 1/2 cups |
| 350 g | 1.74 cups | ~1 and 3/4 cups |
| 400 g | 1.99 cups | ~2 cups |
| 450 g | 2.24 cups | ~2 and 1/4 cups |
| 500 g | 2.49 cups | ~2 and 1/2 cups |
Note: conversions are for US cups (236.6ml) for granulated sugar.
