Choose a multiplier before changing the recipe
This is a weight-based ratio check. Enter the original flour, water, yeast and salt weights in grams, plus your chosen multiplier. The four ingredient labels define this particular dough example; a different recipe needs its own complete list. A zero means the ingredient is intentionally absent, not forgotten. Do not substitute a liquid volume for its weight without measuring an appropriate conversion.
The multiplier has no unit. A factor of 1.75 means that every entered ingredient becomes 175% of its original weight. It does not mean adding 175% to the original amount. A factor below one reduces the recipe. No ingredient should be left at its original weight by accident when the others change.
Exact formula and worked example — SAMPLE DATA
Scaled ingredient weight = original ingredient weight × chosen multiplier
Scaled total mass = sum of every scaled ingredient weight
The following original recipe is fictional. It illustrates arithmetic, not a tested bread formula or a promised baking result.
| Ingredient | Original weight | Factor | Scaled weight |
|---|---|---|---|
| Flour | 400 g | 1.75 | 700 g |
| Water | 260 g | 1.75 | 455 g |
| Yeast | 4 g | 1.75 | 7 g |
| Salt | 8 g | 1.75 | 14 g |
| Total mixture | 672 g | 1.75 | 1,176 g |
The water-to-flour ratio remains 260/400 = 455/700 = 65%. Salt remains 2% of flour weight and yeast 1% in this fictional arithmetic example. These ratios are useful cross-checks; they do not prescribe an appropriate hydration or yeast level for your actual recipe.
Check precision and ingredient handling
A small ingredient can become difficult to weigh accurately after reducing a recipe. If your scale cannot reliably resolve the calculated quantity, do not silently round it to zero or guess a pinch. Choose a feasible batch size or obtain appropriate measuring equipment. Keep the unrounded calculation in your working notes and record any deliberate practical adjustment separately.
Recipe changes are different from scaling. Replacing one flour, changing the liquid or adding fruit can alter how the mixture behaves. A consistent mathematical ratio does not establish that those substitutions work. Record the original recipe version, the factor and any actual changes so that a later result can be interpreted honestly.
What does not scale automatically
Mixing time, fermentation, heating, cooling and equipment capacity do not become reliable by multiplying their old values by 1.75. A larger dough can exceed a mixer’s working capacity; a deeper pan can change heating behavior. Follow appropriate recipe and equipment guidance and test the adjusted process. This page gives no food-safety, storage or elapsed-time assurance.
Finished yield and saleable loss are also separate observations. A total of 1,176 g of mixture does not prove a particular number of baked pieces or their final weight. The recipe-yield calculator owns the count and target-dough-weight planning task. The ingredient-cost calculator helps cost the measured quantity actually used.
Validate your inputs
Use finite, non-negative ingredient weights and a finite positive multiplier. The on-page factor is limited to 1,000 and each ingredient to 1,000,000 g to catch accidental entries; those are software bounds, not equipment recommendations. Include every ingredient in a real recipe. Missing input must be corrected instead of silently becoming zero. The displayed total should equal the sum of the displayed scaled ingredients before rounding.
