Attofarad (aF) and Coulomb (C) measure different electrical quantities. See how they relate and use context values for a physically meaningful result.
Context values
Some unit families need one extra value for a physically accurate result.
The coulomb (C) is the SI unit of electric charge, equal to the charge carried by a steady current of one ampere flowing for one second.
No fixed factor — different physical quantities
Attofarad measures capacitance and Coulomb measures electric charge. These are different physical quantities, so there is no fixed multiplication factor between them. Use Ohm’s law and energy over time: V = I × R, P = V × I, E = P × time.

Compatibility notice
Attofarad (aF) measures capacitance. Coulomb (C) measures electric charge. Because these are different physical dimensions, there is no single fixed factor that converts one directly into the other — a numeric answer would be fabricated and misleading.
Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Enter voltage, current, resistance, and/or hours in the context fields above the result to get a physically accurate value based on the relationship between attofarad and coulomb.
Conversion table
A direct numeric table is not shown here because attofarads and coulombs are not directly proportional. Instead, use the calculator above with context values, or convert within a single dimension using the related conversions below.

How attofarads and coulombs relate
Attofarad and Coulomb belong to different electrical dimensions (capacitance vs. electric charge), so this page does not fabricate a fixed conversion formula. Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Supply the missing context (voltage, current, resistance, or time) in the calculator to compute a real-world equivalent.
Frequently asked questions

About attofarads and coulombs
An Attofarad (aF) equals 1e-18 farad(s), a scaled unit of capacitance used for atto-scale electrical work. The coulomb (C) is the SI unit of electric charge, equal to the charge carried by a steady current of one ampere flowing for one second.
Because attofarad and coulomb describe different electrical quantities, this page provides context-aware guidance instead of a fabricated formula. Use the calculator with real circuit values, or explore the related same-dimension conversions above for direct, exact conversions.
