THE NUMBERS, EXPLAINED
How to use this calculator.
Mass-weighted cocoa-label percentage assuming no mass loss and comparable label definitions. This does not determine tempering compatibility.
Start with your inputs
Enter couverture ingredient masses (g), label cocoa percentages. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Couverture ingredient masses (g) | 200,300 |
| Label cocoa percentages | 50,70 |
A worked example
With the example inputs above, cocoa mass by ingredient (g) is 100, 210. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Cocoa mass by ingredient (g) | 100, 210 |
| Blend mass (g) | 500 |
| Blend cocoa percentage (%) | 62 |
How this is calculated
Cocoa mass by ingredient (g)
Apply each label cocoa percentage to its ingredient mass.
Blend mass (g)
Add ingredient masses.
Blend cocoa percentage (%)
Divide total cocoa mass by blend mass and express as percent.
Symbols and units
- a
- Couverture ingredient masses (g)
- b
- Label cocoa percentages
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
Mass-weighted cocoa-label percentage assuming no mass loss and comparable label definitions. This does not determine tempering 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?
Cocoa mass by ingredient (g); Blend mass (g); Blend cocoa percentage (%). 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: Mass-weighted cocoa-label percentage assuming no mass loss and comparable label definitions. This does not determine tempering 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.
