About Picocoulombs per square metre
The picocoulomb per square metre (pC/m²) equals 10⁻¹² C/m², the scale for surface charge density on lightly charged polymer electret films and semiconductor surface states. Low-dose ion-implanted silicon has surface charge densities of 1-100 pC/m²; piezoelectric polymer films (PVDF) accumulate picocoulombs per square metre at low mechanical stress. 1 pC/m² = 10⁻¹² C/m² = 10⁻³ nC/m².
About Coulombs per square foot
The coulomb per square foot (C/ft²) equals exactly 1/(0.3048)² C/m² ≈ 10.7639 C/m², used in North American electrostatic specifications for insulating flooring, workbench surfaces, and static-dissipative materials. ANSI/ESD standards specify electrostatic charge decay and surface charge limits in C/ft²; antistatic mat and flooring performance is rated in C/ft². 1 C/ft² ≈ 10.764 C/m².
