The resistivity is a material property that describes how well the material isolates electricity. It is measured in units of resistance × length or resistance × area / length, respectively. SI unit is the ohm metre (Ω·m, kg·m3s-3A-2).
The conductivity is a material property that describes how well the material conducts electricity. It is the reciprocal value of resistivity and is measured in units of conductance / length or conductance × length / area. Its SI derived unit is the siemens per metre (S / m, A2s3m-3kg-1).
This converter allows to transform values for the electric resistivity and the electric conductivity in different units into each other.

Usage: Type the value to convert into the field, behind which you find the unit. Move the mouse over a unit or click on it to read its full name. Click on any empty space in the window or on the "calculate" button. Read the result in the other fields. Use the "reset" button to reset your calculation.

Example: What is the electric conductivity of a material (tungsten) with an electric resistivity of 5.6·10-8 Ωm? Type "5.6e-8" into the field in the first row, behind which you find "Ω · m". Click on any empty space in the window or on the "calculate" button. Read the result in the field, behind which "S / m" is written (1.79·107 S / m or 17.9 MS / m).

Remarks:
- Please note the remarks about the representation of numbers..
- There is no warranty for the calculation. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.
