Batch Scaler

Apply a transparent linear batch-volume factor to typed mass, volume, or count quantities without pretending process behavior scales perfectly.

Boundary: Equipment capacity, heating, pressure, sanitation, and process safety must be assessed independently of a quantity multiplier.

Static result contract

Worked example

A production ICU form can progressively enhance this calculator later. The method and representative result remain understandable with no JavaScript.

Method

BEU does not hide the calculation behind a single result number.

Method	Formula	Interpretation boundary
Linear scale factor	`factor = target batch volume / source batch volume; scaled amount = source amount × factor`	Pure proportional arithmetic. Brewing process performance may be nonlinear across system sizes.

Input contract

Input guards keep this foundation implementation bounded. They are not style definitions, legal thresholds, or equipment ratings.

Input	Accepted units / range	Boundary
Source batch volume	l, us gallon	Reference batch volume.
Target batch volume	l, us gallon	Desired comparison volume.

Limits & safety

Linear quantity scaling does not guarantee identical efficiency, losses, evaporation, hopping, yeast behavior, water chemistry, thermal performance, or sensory outcome.

Equipment capacity, heating, pressure, sanitation, and process safety must be assessed independently of a quantity multiplier.
