Cooking Conversion Calculator
Scale a recipe to new servings AND convert a cup amount to grams (or vice-versa) for common baking ingredients.
Result
- Scale multiplier× 1.5000
- Original amount (cups)1.000
- Original amount (grams)120.0
- Original amount (tbsp)16.00
- Original amount (ml)236.6
- Original amount (oz mass)4.233
- Scaled (cups)1.500
- Scaled (grams)180.0
- Density used (g/cup)120
Step-by-step
- Recipe multiplier = new / original = 6 / 4 = 1.5000.
- Convert input to cups: 1 cup = 1.0000 cup.
- Convert input to grams via density: 1.000 × 120 = 120.0 g (or direct mass input if g/oz).
- Apply multiplier: cups → 1.500, grams → 180.0.
How to use this calculator
- Set original and new servings to compute the scale multiplier.
- Pick the ingredient — densities differ a LOT (flour 120 g/cup; honey 340 g/cup).
- Enter the amount in any common unit; the calculator shows it in cups, tbsp, ml, grams, and oz, then applies the multiplier.
- For mass→volume conversions, set "from unit" to grams or ounces.
About this calculator
Two cooking conversions in one tool. Recipe scaling: multiply every ingredient by the ratio of new servings ÷ original servings — works linearly for most things, but reduce leavening (baking powder/soda/yeast) by 10-20% for 3×+ scale-ups. Cup → gram density conversion: 1 cup of flour ≠ 1 cup of sugar in weight because they have different densities. The ingredient picker uses King Arthur Baking's authoritative ingredient-weight chart, which is itself derived from USDA FoodData Central. For baking, weighing in grams is dramatically more accurate than measuring cups — cups vary by how packed the ingredient is. The volume↔mass conversion is the one cooking conversion that genuinely matters.
