Recipe Ratio Calculator
Turn a weight ratio such as 3 parts flour to 2 parts water into gram amounts for the batch you want to make.
Amount: 300.0 g
Amount: 200.0 g
Total: 500.0 g
Parts express a weight ratio. For 3 parts flour to 2 parts water and 500 g total, use 300 g flour and 200 g water. This does not convert cups to grams or adjust cooking time.
How recipe ratios work
Add all the ratio parts, then divide your target total weight by that sum. Multiply the weight of one part by each ingredient’s number of parts. For a 3:2 ratio and 500 g total, each part is 100 g: use 300 g of the first ingredient and 200 g of the second.
If you already know one ingredient weight, switch to “Known ingredient.” The calculator derives the weight of one part from that ingredient and calculates the rest. Use the same weight unit for every ingredient.
Need to change an existing recipe from 8 servings to 12? Use the recipe scaling calculator instead. Ratios describe a recipe’s composition; serving scaling multiplies known ingredient amounts by a factor.
