THE NUMBERS, EXPLAINED
How to use this calculator.
Each row represents the same batch. Unreconciled milk can include retained milk or measurement loss.
Start with your inputs
Enter milk poured by batch (ml), milk served by batch (ml), milk discarded by batch (ml). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Milk poured by batch (mL) | 500,600 |
| Milk served by batch (mL) | 400,450 |
| Milk discarded by batch (mL) | 80,100 |
A worked example
With the example inputs above, usable yield (%) is 77.272727. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Usable yield (%) | 77.272727 |
| Recorded waste (mL) | 180 |
| Unreconciled milk (mL) | 70 |
How this is calculated
Usable yield (%)
Divide served milk by poured milk.
Recorded waste (mL)
Add measured discard.
Unreconciled milk (mL)
Subtract served and discarded milk from poured milk.
Symbols and units
- a
- Milk poured by batch (mL)
- b
- Milk served by batch (mL)
- c
- Milk discarded by 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
Each row represents the same batch. Unreconciled milk can include retained milk or measurement loss.
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?
Usable yield (%); Recorded waste (mL); Unreconciled milk (mL). 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: Each row represents the same batch. Unreconciled milk can include retained milk or measurement loss.
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.
