How to convert any American recipe from cups to grams
American cookbooks and food blogs use cups. The rest of the world uses grams. Converting once means you can reproduce any recipe perfectly, every time.

Why cups are an imprecise unit
A cup is a unit of volume, not weight. The problem is that different ingredients have completely different densities. One cup of honey weighs 340 grams. One cup of all-purpose flour weighs 120 grams. One cup of cocoa powder weighs just 85 grams. The cup is the same. The weight is completely different.
On top of that, the way you fill the cup changes the weight — sometimes dramatically. Converting to grams eliminates all of this uncertainty.
Step-by-step: how to convert a recipe
- List every ingredient with its cup measurement (including fractions like ½ cup or ¼ cup).
- Find the gram-per-cup value for each ingredient on this site — use the search bar or browse by category.
- Multiply: grams per cup × number of cups = total grams. For example, 2½ cups of flour = 2.5 × 120 = 300 grams.
- Note the result next to each ingredient in the recipe. You only need to do this once per recipe.
- Bake with a scale from now on — add each ingredient directly to the bowl, zeroing the scale between each one.
Common fractions converted
| Cup amount | Multiplier |
|---|---|
| ¼ cup | × 0.25 |
| ⅓ cup | × 0.333 |
| ½ cup | × 0.5 |
| ⅔ cup | × 0.667 |
| ¾ cup | × 0.75 |
| 1 cup | × 1 |
| 1½ cups | × 1.5 |
| 2 cups | × 2 |
What about teaspoons and tablespoons?
Small quantities — like 1 teaspoon of baking soda or ½ teaspoon of salt — are best left as volume measurements for most home bakers. At these tiny quantities, the variance is small enough that a measuring spoon is accurate enough. Reserve the scale for tablespoon quantities and above.
The one-time investment
Converting a recipe takes about five minutes the first time. After that, you have a gram-based version you can use forever — no recalculating, no measuring cup variability, no inconsistency. Your favourite American recipes become as reliable as any gram-based recipe.
The takeaway
Converting cups to grams is simple: find the gram-per-cup value for each ingredient, multiply by the cup amount, and write it down. Do it once per recipe and you never need to do it again.
