THE NUMBERS, EXPLAINED
How to use this calculator.
Parts describe a user-tested volume recipe; quantities are proportional and do not predict colour, opacity or compatibility.
Start with your inputs
Enter chosen paint proportions (parts), total paint batch (ml). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Chosen paint proportions (parts) | 2,1,1 |
| Total paint batch (mL) | 100 |
A worked example
With the example inputs above, component paint quantities (ml) is 50, 25, 25. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Component paint quantities (mL) | 50, 25, 25 |
| Normalized component percentages (%) | 50, 25, 25 |
How this is calculated
Component paint quantities (mL)
Divide total batch among components in proportion to their entered parts.
Normalized component percentages (%)
Divide each component parts by total parts.
Symbols and units

- Chosen paint proportions (parts)
- b
- Total paint batch (mL)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Parts describe a user-tested volume recipe; quantities are proportional and do not predict colour, opacity or compatibility.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Component paint quantities (mL); Normalized component percentages (%). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Parts describe a user-tested volume recipe; quantities are proportional and do not predict colour, opacity or compatibility.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
