You can scale by factor or by target total, then review before-correction, after-correction, and rounded values separately.

Batch Scale-Up Calculator (Ratio-Preserving with Loss and Yield)
Scale a formulation without changing its ratios, then apply loss, yield, and minimum charge rounding in one pass. Paste a spreadsheet table and go straight to a scaled batch table, deltas, and CSV or JSON export.
Load a template
Start with a small sample formula so the result flow is visible immediately.
Paste from Excel or Sheets
Paste TSV or CSV data and split it into rows automatically.
Import CSV
Open an existing batch sheet or record file and recalculate it in place.
Loss, yield, and minimum charge rounding are applied in one workflow, so you can reach a practical charging table faster.

How to use
- Paste a formula table or add rows manually for ingredient, amount, unit, and note.
- Choose either factor mode or target-total mode. The target total always refers to the pre-correction total.
- Add loss, yield, and rounding only if needed, so the result moves closer to a practical charging table.
- Review the summary and scaled batch table, then export as TSV, CSV, JSON, or print output.
Scale a lab formula by 10
Input: Water 100 g, NaCl 5 g, Citric Acid 1 g, factor 10
Output: Water 1000 g, NaCl 50 g, Citric Acid 10 g
Match a target total of 12.5 kg
Input: original total 1000 g, target total 12.5 kg, loss 2%, yield 98%, rounding 0.1 g
Output: factor 12.5, scaled total before correction 12500 g, after correction 13010.2 g, after rounding 13010.5 g
Formula with both mass and volume
Input: Resin 900 g, Additive 50 g, Solvent 120 mL, factor 4
Output: factor mode scales each row by 4. Target-total mode warns unless one common approximate density is provided.
Scale factor
The multiplier applied to the original formula. A factor of 10 multiplies every row by 10.
Loss rate
The extra allowance expected during charging or handling. It is added on top of the theoretical amount.
Yield
The fraction you expect to obtain at the end. It is used to back-calculate the amount that must be charged.
Formulas
Pre-correction amount = original amount × scale factorCharge-basis corrected amount = pre-correction amount × (1 + loss / 100) ÷ (yield / 100)Product-basis corrected amount = pre-correction amount ÷ (1 + loss / 100) × (yield / 100)Target-total factor = target total ÷ original totalRounded amount = rounding method(target amount, minimum charge increment)
FAQ
Can I mix g and kg, or mL and L?
Yes. Mixed entries within the same family, such as mg, g, kg or uL, mL, L, are normalized automatically. If mass and volume are mixed together, target-total mode needs one common approximate density.
Can I round to a charging increment?
Yes. Set a minimum charge increment and choose round up, nearest, or down. The tool also shows the total drift caused by rounding.
Is the input saved anywhere?
The last working state and saved snapshots stay only in this browser on this device. Nothing is sent to the server.
Why do I get a warning in target-total mode?
When mass and volume are mixed, the meaning of total quantity is ambiguous. Unless you provide one common approximate density, factor mode is safer.
What is the basic flow from lab batch to production batch?
First scale the formula while keeping the ratio intact. Then apply loss, yield, and rounding to settle on a practical charge amount. Equipment limits and process constraints should still be checked separately.
Notes
- This tool is a formulation scaling aid. It does not evaluate safety, reactivity, heat generation, viscosity change, mixing order, solubility, shear, or equipment capability.
- Before applying the result to a real process, review equipment limits, process design, risk assessment, regulations, and quality specifications separately.
- If you use one common approximate density for a mixed mass-volume formula, treat the result as an estimate rather than an exact physical conversion.
