Common Scenarios

Charge conversion is most commonly seen when comparing battery capacities of electronic devices. When buying a phone or power bank, capacity is usually in mAh; in professional electrical calculations, Coulombs (C) are used.

History & Background

The "Coulomb" is named after French physicist Charles-Augustin de Coulomb, who discovered Coulomb's Law using a torsion balance. "Ampere-hour" originated from the early battery industry.

Conversion Details

Electric charge represents the quantity of electricity. The SI unit is the Coulomb (C). Battery capacity is expressed in Ampere-hours (Ah).

Common conversions: 1 Ah = 3600 C, 1 mAh = 3.6 C.
