Overview of Conductivity and Resistivity Unit Conversion
In the fields of industrial instrumentation and water quality analysis, conductivity and resistivity are core parameters for evaluating the conductive properties of solutions. Different industries and instruments often use different units, such as S/m, mS/cm, µS/cm, Ω·m, Ω·cm, etc., so mastering unit conversion methods is crucial.
This article provides complete conversion formulas, coefficient tables, and online tools to help engineering technicians and procurement personnel quickly complete unit conversions and ensure accurate and consistent data.
Conductivity Unit Conversion
Conductivity indicates the conductive ability of a solution, and its SI unit is siemens per meter (S/m). Common units also include millisiemens per centimeter (mS/cm), microsiemens per centimeter (µS/cm), and picosiemens per meter (pS/m).
Conductivity Unit Conversion Relationships
| Unit | Convert to S/m | Convert to mS/cm | Convert to µS/cm |
|---|---|---|---|
| 1 S/m | 1 | 10 | 10000 |
| 1 mS/cm | 0.1 | 1 | 1000 |
| 1 µS/cm | 0.0001 | 0.001 | 1 |
| 1 pS/m | 1e-12 | 1e-11 | 1e-8 |
Conductivity Conversion Steps
- Enter the conductivity value and select the original unit.
- Select the target unit.
- Click the "Convert Conductivity" button to obtain the result.
Conversion principle: first convert the value uniformly to S/m, then convert it to the target unit.
Resistivity Unit Conversion
Resistivity is the reciprocal of conductivity and indicates a material's ability to impede current. Its SI unit is ohm-meter (Ω·m). Common units also include ohm-centimeter (Ω·cm) and kilo-ohm-centimeter (kΩ·cm).
Resistivity Unit Conversion Relationships
| Unit | Convert to Ω·m | Convert to Ω·cm | Convert to kΩ·cm |
|---|---|---|---|
| 1 Ω·m | 1 | 100 | 0.1 |
| 1 Ω·cm | 0.01 | 1 | 0.001 |
| 1 kΩ·cm | 10 | 1000 | 1 |
Resistivity Conversion Steps
- Enter the resistivity value and select the original unit.
- Select the target unit.
- Click the "Convert Resistivity" button to obtain the result.
Conversion principle: first convert the value uniformly to Ω·m, then convert it to the target unit.
Conversion Between Conductivity and Resistivity
Conductivity (σ) and resistivity (ρ) are reciprocals of each other, and the relationship formulas are:
Resistivity (ρ) = 1 / Conductivity (σ)
When using the interchange tool, enter the value and select the type (conductivity or resistivity) and unit, then click "Convert to Opposite Quantity" to obtain the corresponding result.
Interchange Examples
- If the conductivity is 0.01 S/m, then the resistivity is 100 Ω·m.
- If the resistivity is 10 Ω·cm, then the conductivity is 10 S/m (i.e., 10000 µS/cm).
