Electric Charge Converter
Convert between 10 electric charge units.
About Electric Charge
Electric charge is measured in coulombs, one of which is an ampere flowing for one second. Batteries are rated in ampere-hours instead, and 1 Ah is 3,600 coulombs, so a 3,000 mAh phone battery holds about 10,800 C. At the far end of the scale is the elementary charge — the charge on a single electron — at 1.602 × 10⁻¹⁹ C.
