THE NUMBERS, EXPLAINED
How to use this calculator.
Measured physical weight summary only; does not certify declared-weight compliance.
Start with your inputs
Enter gross sample weights (g), container tare weights (g), measured drained food weights (g). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Gross sample weights (g) | 550,600 |
| Container tare weights (g) | 50,50 |
| Measured drained food weights (g) | 300,330 |
A worked example
With the example inputs above, net weights (g) is 500, 550. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Net weights (g) | 500, 550 |
| Average drained weight (g) | 315 |
| Drained fraction of total net weight (%) | 60 |
How this is calculated
Net weights (g)
Subtract each container tare from gross sample weight.
Average drained weight (g)
Average drained food measurements.
Drained fraction of total net weight (%)
Divide total drained food by total net contents.
Symbols and units
- a
- Gross sample weights (g)
- b
- Container tare weights (g)
- c
- Measured drained food weights (g)
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
Measured physical weight summary only; does not certify declared-weight compliance.
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?
Net weights (g); Average drained weight (g); Drained fraction of total net weight (%). 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: Measured physical weight summary only; does not certify declared-weight compliance.
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.
