Recipe Scaler

Enter the original and target servings, scale each amount, then use weight-based ingredient conversion or pan scaling when the recipe changes format as well as yield.

Prefer weight when repeatability matters

Mass↔volume estimates depend on ingredient density and measuring technique. Pan substitutions can also change bake time and browning even when volume ratios match, while fermentation timing depends on temperature and dough conditions rather than one percentage alone.

Scale by servings or multiplier without losing common fractions

Quick ½×/2×/3× presets and best-fit fractions up to the selected denominator keep 1/3 and 2/3 from being forced onto a 1/16 grid.

Designed for fast kitchen use

The v263 interface keeps primary inputs and result trust in the first workflow, uses larger mobile controls, kitchen-friendly fractions where useful, and exposes the governing assumption instead of burying it below the calculator.
