Rendered to 6 significant figures.
Formula
Formula
kC = C × 0.001
Multiply any value in coulombs by 0.001 to obtain the value in kilocoulombs.
Worked example
Convert 1000 C to kC.
- 01Start with 1000 C.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kC.
Result1000 C = 1 kC

FAQ
What is the conversion factor from C to kC?
1 C equals 0.001 kC. To convert, multiply the value in coulombs by 0.001.
How do I convert 1 C to kC?
1 C = 0.001 kC. For any value, multiply by 0.001.
How do I convert kC back to C?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kC = 1000 C.
When would I need to convert coulomb to kilocoulomb?
Electric-charge conversions between C and kC appear in battery capacity specification (A·h, mA·h), electroplating and electrochemistry (coulombs of charge transferred), and capacitor energy calculations. 1 A·h is exactly 3600 C — the conversion is a linear factor and does not depend on voltage, current profile or chemistry.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
