Ingredient Measurement Converter
Recipe Scaler
Enter your recipe’s ingredients and original serving count, then set how many servings you need — every quantity scales automatically.
Why ingredient density matters
A cup is a unit of volume, but recipes often need a weight (grams or ounces) for accuracy. The catch: a cup of all-purpose flour weighs roughly 120g, while a cup of honey weighs around 340g, because density differs by ingredient. A generic volume-to-weight converter that ignores this gets baking recipes wrong — sometimes badly enough to ruin the result. That’s why every conversion here is tied to a specific ingredient’s density rather than a single universal factor.
Common measurement mistakes
- Scooping flour directly from the bag packs it in and can add 20–30% more than a spooned-and-leveled cup.
- Treating fluid ounces and weight ounces as the same thing — they aren’t, and mixing them up throws off both baking and nutrition math.
- Assuming one conversion factor works for every ingredient — sugar, flour, and butter all convert differently between cups and grams.
Frequently asked questions
Why isn’t 1 cup always 240 grams?
Because a cup measures volume, not weight. Different ingredients pack differently into that volume, so the gram weight of one cup changes depending on what you’re measuring.
Can I scale a recipe with mixed units?
Yes. The recipe scaler multiplies each ingredient’s quantity by the same ratio regardless of unit, so cups, grams, and tablespoons in the same recipe all scale correctly together.
