A SMALL TOOL WITH ONE JOB
About Batchscale.
Batchscale turns a recipe’s original quantities into a new batch using one transparent multiplier.
Choose a serving count or compare rectangular and circular pan areas at the same filled depth. Enter each ingredient in the unit used by the original recipe. The tool preserves those units and shows simple fractions only when the calculation supports them.
It does not convert cups to grams, choose ingredient substitutions, estimate nutrition, or scale cooking time and temperature.
Free to use
There is no subscription, checkout or account. The calculator is part of an independently operated collection of free planning tools. Each site focuses on one calculation so its assumptions stay easy to inspect.
How the tool is maintained
The calculation method is described in the worked guide. Automated checks cover conversion factors, example results and invalid inputs. A model can still miss a practical detail; use the guide to decide whether its assumptions fit your situation.
