Description
Scale a supplied per-100-gram nutrient value to edible mass.
Dietary arithmetic depends on as-purchased versus edible mass, per-serving versus per-100-gram bases, measured versus trace states and recall periods. A recorded allergen list is not a verified allergen-free declaration. Portion counts, label intervals and mass differences use supplied assumptions rather than establishing actual intake or nutritional suitability.
Scale a supplied per-100-gram nutrient value to edible mass.
When to use this tool
Use Nutrient Contribution Per Edible Gram when you already have nutrientPer100Grams, edibleGrams and need to scale a supplied per-100-gram nutrient value to edible mass.
How to use the tool and how it works
- Enter nutrientPer100Grams, edibleGrams. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nutrientContribution. Use the output convention below.
Require nutrientPer100Grams and edibleGrams>=0; return nutrientPer100Grams/100*edibleGrams.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| nutrientPer100Grams | Nonnegative nutrient amount in the caller's nutrient unit per 100 edible grams. | Required. Finite number; minimum 0. |
| edibleGrams | Edible Grams | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nutrientContribution | Nutrient Contribution | Required. Finite number. |

}Limitations and assumptions
- The nutrient unit is preserved and mass basis must match. No food composition, bioavailability, nutrient requirement or suitable intake is determined.
- 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
Check original food labels, composition sources, ingredient/allergen information and dietary records before combining amounts. Use a complete appropriately interpreted dietary assessment when requirements or suitable intake matter; local scaling and source labels do not make those judgments.
