These are common reference weights. Real value can vary.

1 cup ≈ 240 mL
Quick tip
For baking, weighing is always more accurate than cups. Use this converter when the recipe is written in cups but you want grams — or vice versa.
Formulas used
cups = grams ÷ grams_per_cup
grams = cups × grams_per_cup
mL ≈ cups × 240
The only thing that changes is grams_per_cup, which depends on the ingredient’s density and how it is packed.
Common grams to cups conversions
| Ingredient | 1 cup (g) | 100 g → cups | 250 g → cups |

Rounded to 2–3 decimals. Always check the recipe’s own conversion if it provides one.
Why “grams to cups” is not universal
A lot of sites give a single answer like “1 cup = 128 g”. That’s fine only for water. Real recipes use flour, sugars, fats, nuts — all different densities. That’s why this calculator makes you pick the ingredient first.
Best practices for bakers
- Weigh if you can (grams)
- If you must use cups, always say which ingredient it is
- For flour, scooped vs spooned can change 1 cup by 10–20%
- Brown sugar is often packed → heavier per cup
FAQ
1. Which cup are you using?
We use the US cup of 240 mL as a general kitchen reference. If your region uses 250 mL cups, results will be slightly different.
2. Can I enter my own grams per cup?
Yes. Pick “Custom…” in the dropdown and enter the exact grams per cup from your package or recipe. The tool recalculates instantly.
3. Why do my numbers look slightly different from another site?
Each site picks its own reference density (e.g. 1 cup sugar = 198 g vs 200 g). Differences of a few grams are normal and not critical for most home cooking.
