About Abcoulombs per square centimetre
The abcoulomb per square centimetre (abC/cm²) is the surface charge density unit of the CGS-EMU system, equal to 1 abC / 1 cm² = 10 C / 10⁻⁴ m² = 10⁵ C/m². It appears in nineteenth-century electromagnetic engineering texts on telegraph cable and dynamo analysis; the abC/cm² is the natural surface density unit when using abamperes and centimetres. 1 abC/cm² = 10⁵ C/m² = 100 kC/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.
