Description
Label a supplied electrode area with its recorded area basis.
Electrochemical quantities require explicit electrode references, current sign, area definition and time basis. Geometric area differs from active-area conventions, charge differs from charge equivalents, and a logarithmic current coordinate needs a same-unit reference magnitude. Local sign changes and coordinate terms do not fit kinetics or establish a valid experiment.
Label a supplied electrode area with its recorded area basis.
When to use this tool
Use Electrode Geometric Active Area Label when you already have areaSquareCentimeters, areaBasis and need to label a supplied electrode area with its recorded area basis.
How to use the tool and how it works
- Enter areaSquareCentimeters, areaBasis. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require areaSquareCentimeters>=0 and areaBasis geometric, electrochemically-active, BET or other; append the basis label.1
| Input field | Meaning and units | Accepted input |

| areaBasis | Supplied area-definition label; no conversion between geometric, active or BET areas. | Required. Text; one of "geometric", "electrochemically-active", "BET", "other"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- No conversion between area definitions, adsorption analysis, active-area measurement or validity of a chosen basis is established.
- 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
Inspect calibrated instrument records, reference-electrode details, area definitions and the complete experiment before interpreting results. Use the full electrochemical model and verified operating conditions when a local current, charge, sweep or impedance-representation term cannot answer the scientific question.
