Description
Return remaining volume and its fraction of capacity.
Food quantities depend on whether their basis is gross, edible, drained, wet, dry or solid mass. Changing the denominator can change a reported concentration or yield without changing the actual sample or proving anything about its safety.
Return remaining volume and its fraction of capacity.
When to use this tool
Use Package Fill Headspace Share when you need a stated food-mass, composition-basis or yield calculation.
How to use the tool and how it works
- Enter fillVolume, packageVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read headspace, headspaceShare. Use the output convention below.
Require positive package volume and fill from zero through capacity. Return remaining volume and its fraction of capacity.1

| packageVolume | Package Volume | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| headspace | Headspace | Required. Finite number. |
| headspaceShare | Headspace Share | Required. Finite number. |

}Limitations and assumptions
- Headspace is a geometric remainder, not an assessment of acceptable fill, microbial risk, gas composition or package safety.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Reconcile measured quantities and preparation records on a common basis. Use the appropriate laboratory, nutritional or safety assessment when arithmetic alone cannot establish the intended property.
