Formula
Formula
μC = C × 1000000
Multiply any value in coulombs by 1000000 to obtain the value in microcoulombs.
Worked example
Convert 1 C to μC.
- 01Start with 1 C.
- 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 μC.
Result1 C = 1.00000e+6 μC

FAQ
What is the conversion factor from C to μC?
1 C equals 1000000 μC. To convert, multiply the value in coulombs by 1000000.
How do I convert 1 C to μC?
1 C = 1.00000e+6 μC. For any value, multiply by 1000000.
How do I convert μC back to C?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 μC = 1e-6 C.
When would I need to convert coulomb to microcoulomb?
Electric-charge conversions between C and μC 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?
Yes. Both C and μC are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
