Understanding Surface Charge Density

Surface charge density (σ) is a measure of electric charge per unit area of a surface. It describes how much charge is accumulated over a given area.

The SI unit for surface charge density is Coulombs per square meter (C/m²).

Common Surface Charge Density Units
Unit Name Symbol Relation to C/m² (Approx.)
Coulomb/square meter C/m² Base unit (1 C/m²)
Coulomb/square centimeter C/cm² 10,000 C/m²
Microcoulomb/square meter µC/m² 1 × 10-6 C/m²
Elementary charge/square meter e/m² 1.602 × 10-19 C/m²
Abcoulomb/square meter abC/m² 10 C/m²
