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.
About Millicoulombs per square metre
The millicoulomb per square metre (mC/m²) equals 10⁻³ C/m², the scale for triboelectric charging of common plastics and electrostatic spray-coating processes. Rubbed polytetrafluoroethylene (PTFE) accumulates 1-10 mC/m²; electrostatic powder coating guns deposit 1-5 mC/m² on grounded work pieces; thundercloud base charge density before lightning is 1-5 mC/m². 1 mC/m² = 10⁻³ C/m² = 10³ µC/m².
