Electric Charge Converter
Convert electric charge between picocoulombs, microcoulombs, coulombs, milliampere-hours, and ampere-hours locally in your browser.
Convert electric charge between picocoulombs, nanocoulombs, microcoulombs, millicoulombs, coulombs, kilocoulombs, milliampere-hours, and ampere-hours. Zero is a valid charge.
Conversions run locally in your browser; your charge is not uploaded or stored.
Convert one electric charge value into the units you need.
Enter a non-negative electric charge value and choose its unit to see the equivalent picocoulombs, nanocoulombs, microcoulombs, millicoulombs, coulombs, kilocoulombs, milliampere-hours, and ampere-hours. Zero is valid. It runs locally in your browser, so your value is not uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Which electric charge units can I convert?
Enter an electric charge in picocoulombs, nanocoulombs, microcoulombs, millicoulombs, coulombs, kilocoulombs, milliampere-hours, or ampere-hours. The converter returns the equivalent value in all eight units using 1 nC = 1000 pC, 1 µC = 1000 nC, 1 mC = 1000 µC, 1 C = 1000 mC, 1 kC = 1000 C, 1 mAh = 3.6 C, and 1 Ah = 3600 C.
Can I convert zero or decimal charge values?
Yes. Zero is a valid electric charge, and decimal values are accepted. Negative values are rejected because a charge magnitude cannot be less than zero. Results show up to six decimal places when needed.
What happens with very large charge values?
The converter shows an error when the entered charge is too large to convert safely, instead of returning an unreliable rounded result.
Does my charge leave my browser?
No. The conversion and copy action run locally in your browser. CodeASystem does not upload or store the value you enter.
