1 mAh = 3.6 C
1 Milliampere-hour (mAh) = 3.6 Coulomb (C).
If you want to reverse convert, use Coulomb → Milliampere-hour. 1 C = 0.27777777777778 mAh. You can also explore the full Electric Charge converter page for more cross conversions.
Conversion formula
Milliampere-hour to Coulomb formula: value in C = value in mAh × 3.6.
Coulomb to Milliampere-hour formula: value in mAh = value in C × 0.27777777777778.
How to convert Milliampere-hour to Coulomb
To convert Milliampere-hour to Coulomb, multiply the value in mAh by 3.6. This gives the result in C.
For example, 1 mAh = 3.6 C and 10 mAh = 36 C.
What is Milliampere-hour?
Milliampere-hour (mAh): Smaller battery-charge capacity scale, common on portable devices. Battery energy also depends on voltage; an Ah or mAh value alone does not give watt-hours. 1 mAh = 0.001 Ah = 3.6 C.
What is Coulomb?
Coulomb (C): SI charge, equivalent to one ampere flowing for one second. Battery energy also depends on voltage; an Ah or mAh value alone does not give watt-hours. 1 C = 1 A·s; 3600 C = 1 Ah.
FAQ
How many coulomb are in 1 milliampere-hour?
There are 3.6 C in 1 mAh.
Why can conversion results differ slightly?
Check the unit definition and rounding. US and imperial measures can differ; rounding intermediate values can also change the final digits.
How do I convert milliampere-hour to coulomb?
Multiply the value in mAh by 3.6 to get the value in C.
Milliampere-hour → other Electric Charge units
- 1 milliampere-hour → ampere-hour = 0.001 ampere-hour
