Milliampere Hours to Coulombs: 1 mAh equals 3.6 C. To convert milliampere hours to coulombs, multiply by 3.6 (C = mAh × 3.6). For example, 10 mAh = 36 C.
How to Convert Milliampere Hours to Coulombs
To convert from milliampere hours to coulombs, multiply the value by 3.6. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Milliampere Hours to Coulombs:
C = mAh × 3.6 - Coulombs to Milliampere Hours:
mAh = C ÷ 3.6

Understanding the Units
What is a Milliampere Hour?
An ampere-hour equals exactly 3,600 coulombs — a current of one ampere flowing for one hour. It is the standard battery-capacity rating.
Common contexts: battery capacity, power tools, EV.
What is a Coulomb?
The coulomb is the SI derived unit of electric charge, equal to the charge transported by one ampere in one second (1 C = 1 A·s).
Named after Charles-Augustin de Coulomb (1736–1806), French physicist who quantified the electric force law.
Common contexts: electrostatics, chemistry.
