About Gigacoulombs per square metre
The gigacoulomb per square metre (GC/m²) equals 10⁹ C/m², a value with no engineering realisation, used only in astrophysical and theoretical plasma models. Magnetar magnetosphere charge sheet densities, pulsar polar cap surface charge, and theoretical cosmic string surface charge are described at GC/m² scales in research literature. 1 GC/m² = 10⁹ C/m² = 10³ MC/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.
