About electric charge units
Convert coulombs, ampere-hours, mAh, faradays and elementary charges.
Battery capacity in mAh is a charge, not an energy — multiply by the cell voltage before comparing packs of different voltages.
Dimensional formula: I T. Every conversion on this page goes through the coulomb, using exact fractions rather than decimal approximations. Read how that works →
