Calculate the resistivity of a material given its resistance, length, and cross-sectional area. Resistivity is an intrinsic property that quantifies how strongly a material opposes current.
Enter your values below
Measured resistance of the material sample.
Length of the conductor in meters.
Cross-sectional area in square millimeters.
How this calculator works
Resistivity rho is the resistance R times cross-sectional area A divided by length L. It is measured in ohm-meters and depends on temperature and material composition.
