Description
Calculate a supplied pigment-mass portion.
Studio records combine critique categories, time allowances, grid scales, nominal storage counts and permission assertions. A linear enlargement factor must be squared for area, while slot counts do not establish safe physical storage. Supplied rubric labels and participation records do not assess learning or artistic quality.
Calculate a supplied pigment-mass portion.
When to use this tool
Use Art Supply Pigment Portion Weight when you already have totalPigmentMass, portionFraction and need to calculate a supplied pigment-mass portion.
How to use the tool and how it works
- Enter totalPigmentMass, portionFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read portionMass. Use the output convention below.
Require totalPigmentMass>=0 and portionFraction in [0,1]; multiply them.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| totalPigmentMass | Total Pigment Mass | Required. Finite number; minimum 0. |
| portionFraction | Portion Fraction | Required. Finite number; minimum 0; maximum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| portionMass | Portion Mass | Required. Finite number. |

}Limitations and assumptions
- Mass units and composition are supplied. This does not mix pigments, infer color, verify toxicity or recommend a safe material or amount.
- 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
Review the actual classroom, materials, work, rubric and permissions. Use complete educational and physical assessment when local labels, counts or duration budgets cannot establish access, suitable instruction or safe studio arrangements.
