Your formula
Original recipe
A unit can be one loaf, jar, bottle, bar, dozen, pan, or any consistent finished yield.
Ingredients
Use entries like 2, 1.5, 1/2, or 2 1/4.
How it works
One ratio, applied consistently.
The scale factor is your target yield divided by the original yield. Every ingredient quantity is multiplied by that same factor, preserving the recipe's proportions.
target yield÷original yield=scale factor
Common questions
Recipe scaling, explained simply.
Can I enter fractions?
Yes. Use formats such as 1/2, 1 1/2, 0.5, or 2.25. Results are rounded to useful kitchen-friendly values when possible.
Does the calculator convert cups to grams?
No. Unit conversion depends on ingredient density. This calculator preserves the unit you enter and scales only the quantity.
Is this only for food recipes?
No. It works for soap, candles, cosmetics, spice blends, garden products, and any formula where ingredients scale proportionally.

How to use the Recipe & Batch Scale Calculator
Resize any recipe and recalculate every ingredient. The calculator runs privately in your browser and is designed to make the assumptions behind the answer visible.
What to have ready
Start with a tested baseline formula, measured weights, the unit used by the full batch, and your actual finished yield or process loss.
How to use the result
Treat the output as a controlled batch draft. Record the assumptions, run a small test, and approve the result only after checking quality and safety.

Batch production and records
A production record is the story of one batch: what you planned, what you used, what happened, and how much good product came out.
