Conversion History
Unit Information
Coulomb (C)
The SI unit of electric charge. One coulomb is equal to the charge transported by a constant current of one ampere in one second.
Milliampere-hour (mAh)
Commonly used to measure battery capacity. 1 mAh = 3.6 coulombs. Represents the charge transferred by a current of one milliampere flowing for one hour.
Ampere-hour (Ah)
Used for larger batteries. 1 Ah = 3600 coulombs. Represents the charge transferred by a current of one ampere flowing for one hour.
Electrostatic unit (esu)
A unit of charge in the CGS system. 1 esu ≈ 3.3356 × 10⁻¹⁰ coulombs. Also known as statcoulomb or franklin.
Conversion Formulas
General Conversion
All conversions are done through coulombs as the intermediate unit. First convert from source unit to coulombs, then from coulombs to target unit.
To Coulombs
mAh → C: value × 3.6
Ah → C: value × 3600
esu → C: value × 3.3356×10⁻¹⁰
F → C: value × 96485.3399
emu → C: value × 10
e → C: value × 1.602176634×10⁻¹⁹
From Coulombs
C → mAh: value ÷ 3.6
C → Ah: value ÷ 3600
C → esu: value ÷ 3.3356×10⁻¹⁰
C → F: value ÷ 96485.3399
C → emu: value ÷ 10
C → e: value ÷ 1.602176634×10⁻¹⁹
