Scale any recipe.
Convert any measurement.
Enter your servings to scale a recipe up or down, or switch cups, grams, ounces and millilitres for any ingredient.
Scaling changes the amounts, not the cooking temperature or time. See how to scale a recipe for why.
Volume-to-weight conversions use standard densities. A cup of flour (125 g) is lighter than a cup of sugar (200 g) — that is why the ingredient matters.

Ingredient-aware
A cup of flour is not a cup of honey. Pick the ingredient and cup-to-gram maths is handled for you.
How to scale a recipe
Three simple steps — or let the tool do it for you.
Find the multiplier
Divide the servings you want by the servings the recipe makes. From 4 to 6 servings, that is 6 ÷ 4 = 1.5.
Multiply every ingredient
Apply the multiplier to each amount. 200 g flour × 1.5 = 300 g.
Tidy up for baking
Keep the temperature, adjust the time only slightly, and go easy on salt and leaveners. Read the full guide →
Quick cup-to-gram reference
Weighing is more accurate than scooping. Here are the most common one-cup weights.
| Ingredient | 1 cup | 1/2 cup | 1/4 cup |
|---|---|---|---|
| All-purpose flour | 125 g | 63 g | 31 g |
| Granulated sugar | 200 g | 100 g | 50 g |
| Brown sugar (packed) | 213 g | 107 g | 53 g |
| Butter | 227 g | 113 g | 57 g |
| Rolled oats | 90 g | 45 g | 23 g |
Frequently asked questions
How do I scale a recipe up or down?
Divide the desired servings by the original servings to get a multiplier, then multiply every ingredient amount by it. For example, going from 4 to 6 servings gives a multiplier of 1.5, so 200 g becomes 300 g. Our scaler above does it automatically.
Why does the ingredient matter when converting cups to grams?
Because a cup measures volume, not weight. A cup of flour weighs about 125 g while a cup of granulated sugar weighs about 200 g. Selecting the right ingredient gives an accurate conversion.
How many grams is 1 cup of flour?
One US cup of all-purpose flour is about 125 g. Bread flour is closer to 127 g and cake flour about 114 g.
Do I scale cooking time too?
Not directly. Scaling amounts usually keeps the temperature and time the same, though larger batches may need a little longer and deeper pans. See our scaling guide.
