Enter the resistivity and the thickness into the Calculator. The calculator will evaluate the Sheet Resistance.
Sheet Resistance Formula
Rs = R / T
Variables:
- Rs is the Sheet Resistance ()
- R is the resistivity
- T is the thickness
To calculate Sheet Resistance, divide the resistivity by the thickness.

FAQs
What is resistivity and how is it measured?
Resistivity is a measure of a material’s ability to resist electric current. It is measured in ohm-meters (Ω·m) and can be determined by the material’s inherent properties, its temperature, and the presence of impurities.
Why is thickness important in calculating sheet resistance?
Thickness is crucial because sheet resistance is directly proportional to the resistivity of the material and inversely proportional to its thickness. A thinner material will have higher sheet resistance, assuming constant resistivity.
Can sheet resistance be used to measure the quality of conductive materials?
Yes, sheet resistance is a key parameter in evaluating the quality of conductive materials. Lower sheet resistance indicates better conductivity, which is desirable in materials used for electrical and electronic applications.
How does temperature affect resistivity and sheet resistance?
Temperature has a significant impact on resistivity and, consequently, on sheet resistance. For most materials, resistivity increases with temperature, leading to higher sheet resistance. This is due to the increased scattering of charge carriers at higher temperatures.
