Description
Use (value ± uncertainty) unit when shared, otherwise repeat the unit after each supplied text.
Measurement uncertainty notation needs a declared numerical scale, unit and interpretation. Parenthesized digits can refer to the last written places, while a coverage-factor suffix is only a label unless an uncertainty calculation supports it.
Use (value ± uncertainty) unit when shared, otherwise repeat the unit after each supplied text.
When to use this tool
Use Plusminus Uncertainty Unit Sharing when you need the specified uncertainty-text layout or last-place conversion.
How to use the tool and how it works
- Enter value, uncertainty, unit, shared. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read text. Use the output convention below.
Require a nonempty unit string. Use (value ± uncertainty) unit when shared, otherwise repeat the unit after each supplied text.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| value | Value under the stated unit, type, and placeholder convention. | Required. Text; maximum UTF-16 length 8192. |
| uncertainty | Supplied uncertainty on the stated measurement basis, not estimated by this tool. | Required. Text; maximum UTF-16 length 8192. |
| unit | Unit | Required. Text; maximum UTF-16 length 8192. |
| shared | Shared | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| text | Literal formatted output under the stated grammar and display convention. | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"value": "12",
"uncertainty": "2",
"unit": "m",
"shared": true
},
"output": {
"text": "(12 ± 2) m"
}
}Limitations and assumptions
- Value and uncertainty are text, not validated measurements; the formatter does not estimate uncertainty or verify dimensional compatibility.
- 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.
Alternative or Complementary methods
Use an appropriate uncertainty analysis and reporting convention for real measurements. Verify units, decimal alignment, uncertainty type and coverage meaning separately from formatting.
