Baking Conversions: Cups to Grams (and Back)
Updated June 2026
Cups, grams, ml, tbsp & more.
Following a recipe in the wrong units is a recipe for disaster. The catch: a cup is a volume, but grams are a weight — so the conversion depends on the ingredient.
Why one cup isn't always the same grams
A cup of flour is light and fluffy; a cup of honey is dense and heavy. Same volume, very different weight. That's why "1 cup = 240g" is wrong for most ingredients — you need the right number per ingredient.
Common cup-to-gram conversions
| Ingredient | 1 cup ≈ |
|---|---|
| All-purpose flour | 125 g |
| Granulated sugar | 200 g |
| Brown sugar (packed) | 220 g |
| Butter | 227 g |
| Water / milk | 237 / 244 g |
| Honey | 340 g |
Quick volume conversions
These never change, since they're volume-to-volume:
- 1 cup = 16 tablespoons = 237 ml
- 1 tablespoon = 3 teaspoons = 15 ml
- 1 teaspoon = 5 ml

Frequently asked questions
How many grams is a cup of flour?
About 125g of all-purpose flour, though it varies a little with how you scoop. Spooning flour into the cup is more accurate than packing it.
Why do bakers prefer grams?
Weighing is far more precise than scooping cups, which is why serious baking recipes list grams — small differences matter.
