Convert Coulombs per square foot (C/ft²) to Attocoulombs per square metre (aC/m²) instantly and accurately.
Conversion Formula
aC/m² = C/ft² × 1.076391042e+19
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 Attocoulombs per square metre
The attocoulomb per square metre (aC/m²) equals 10⁻¹⁸ C/m², the scale for areal charge density on individual molecular monolayers measured by Kelvin probe force microscopy. A single elementary charge on a 1 µm² area gives about 0.16 aC/m²; contact potential distributions in organic photovoltaic blends correspond to aC/m²-scale surface charge. 1 aC/m² = 10⁻¹⁸ C/m² = 10⁻³ fC/m².
