  • Sheet Resistance Equations and Theory | Complete Guide ...

    Sheet resistance ( RS) is commonly defined as the resistivity ( ρ) of a material divided by its thickness ( t ): The units of this equation resolve to ohms (Ω); however, it actually represents the resistance between opposite sides of a square of a material (rather than bulk resistance). As such the units Ω/ (ohms per square) are commonly used.
