Free Charge Converter Tool

Convert between 6 supported units including Coulomb (C), Millicoulomb (mC), Microcoulomb (µC) with adjustable precision and a documented conversion methodology.

What this converter covers

Convert electric charge between coulombs, millicoulombs, microcoulombs, ampere-hours, milliampere-hours, and faradays.

Worked example

1 Ampere-hour (Ah) = 3600 Coulomb (C)

Important unit notes

•Ampere-hour is a unit of electric charge, not electrical energy.
•The faraday represents the charge of one mole of electrons using the molar Faraday constant.

Conversion factors are maintained against documented standards and definitions. Some displayed decimals are rounded for readability.How accuracy is handled·Sources
