Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Convert electric charge across 12 units: SI (C, mC, μC, nC, pC, kC), CGS (abcoulomb = 10 C, statcoulomb = 3.336×10⁻¹⁰ C), and practical (faraday = 96,485 C, A·h = 3600 C, mA·h = 3.6 C, e = 1.602×10⁻¹⁹ C). Battery capacity in mA·h; electrochemistry uses faradays. 100% browser-based.

How to Use

  1. 1Type an electric charge value (e.g. 1 for 1 coulomb)
  2. 2Select your starting unit (e.g. C, mC, mA·h, statcoulomb, faraday)
  3. 3Select your target unit - the result appears instantly
  4. 4All 12 conversions appear across SI, CGS, and Practical groups
  5. 5Hover any row to copy or use as input; click ⇄ to swap
  6. 6Enable Sci notation for elementary charge (e = 1.602×10⁻¹⁹ C)
  7. 7Open 'Common charge conversions' for battery and electrochemistry references
