Description
Return conductance density and its reference-area equivalent.
Membrane electrical quantities distinguish total from area-specific properties, concentration ratios from activities and single-ion from multi-ion models. Local capacitance, current or potential terms require compatible sign, valence, temperature and unit conventions without themselves validating a biological membrane.
Return conductance density and its reference-area equivalent.
When to use this tool
Use Membrane Area Conductance Basis when evaluating the stated membrane, ionic or area-basis term.
How to use the tool and how it works
- Enter totalConductance, area, referenceArea. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read conductancePerArea, referenceConductance. Use the output convention below.
Return conductance density and its reference-area equivalent. Require totalConductance >= 0 and both areas > 0; conductancePerArea = total/area, referenceConductance = conductancePerArea*referenceArea.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| totalConductance | Total Conductance | Required. Finite number; minimum 0. |
| area | Area | Required. Finite number; strictly above 0. |
| referenceArea | Reference Area | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| conductancePerArea | Conductance Per Area | Required. Finite number. |
| referenceConductance | Reference Conductance | Required. Finite number. |

}Limitations and assumptions
- This assumes a uniform area basis; no ionic selectivity, membrane state or measurement calibration 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
Use verified concentrations, activities, geometry and electrical calibration with the appropriate complete membrane/channel model for physiological interpretation.
