Formula
Milliampere-hour to Coulomb conversion: 1 mAh = 3.6 C coulombs = milliampere-hours × 3.6 1 C = 0.2777777778 mAh milliampere-hours = coulombs × 0.2777777778
Example
Example: Convert 10 mAh to C: 10 mAh × 3.6 = 36 C So, 10 mAh is about 36 C. To convert back, multiply by 0.2777777778: 36 C × 0.2777777778 = 10 mAh.
