Description
unitFactor must be target units per source unit, including any required scale conversion.
Environmental measurements can require background subtraction, recovery correction, calibration or a common reference basis. Corrected values can be signed; a numerical correction is separate from detection, analytical validity and health interpretation.
unitFactor must be target units per source unit, including any required scale conversion.
When to use this tool
Use Household Exposure Unit Factor when checking a supplied measurement correction, comparison or calibration term.
How to use the tool and how it works
- Enter recorded, unitFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read converted. Use the output convention below.
Require positive unitFactor and return converted = recorded*unitFactor. unitFactor must be target units per source unit, including any required scale conversion. The recorded input is a finite signed number.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recorded | Recorded | Required. Finite number. |
| unitFactor | Explicit multiplicative conversion into the requested output unit; not inferred. | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| converted | Converted | Required. Finite number. |

}Limitations and assumptions
- No unit names or dimensional compatibility are checked. This is a multiplicative conversion only, so it cannot represent an offset conversion or infer an exposure or health threshold.
- 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
Use the relevant analytical method, quality-control records and uncertainty model before classifying a corrected measurement.

Convert commonBasisValue = reportedConcentration*sourceBasisFactor and referenceBasisValue = suppliedReferenceValue*referenceBasisFactor, then return gap = commonBasisValue-referenceBasisValue.
