About the Coulomb to Milliampere-hour conversion
The conversion factor from Coulomb (C) to Milliampere-hour (mAh) is 0.27778, meaning 1 C = 0.27778 mAh and inversely 1 mAh = 3.6 C. That makes the Milliampere-hour the larger of the two units in the electric charge category, where the SI base unit is the coulomb. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
