Recipe Scaling
Scale ingredient amounts from original servings to target servings.
Your numbers
Scale factor
Units remain unchanged. Cooking time, seasoning and leavening may not scale linearly.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use q = xB/A. x is an original ingredient amount, A is original servings, and B is target servings. Each scaled amount q retains that ingredient's original unit.

Scope and limitations
Units remain unchanged. Cooking time, seasoning and leavening may not scale linearly.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
