How do I scale a bench trial up to a batch?
Every line keeps its share of the trial and is multiplied by the same factor, and the leftover milligram goes to the line with the largest fraction so the batch weighs exactly what you asked for.
Enter the trial as you weighed it. The proportions are what matter, so a trial of 5 g and a trial of 5,000 g scale to the same batch.
| Material (optional) | Trial grams | Share of the trial | Batch grams |
|---|
Scaling is the arithmetic. What a bigger batch also changes is what the formula costs and what a compliance limit is judged against, and neither of those is on this page, because both need the materials behind the numbers. The bench recomputes them from the same lines, and at the scale weighs one material at a time, offering to rescale everything still to come the first time you overpour.
