Enter coulombs (C) or microcoulombs (µC) into the calculator to convert to the other value.
Assumptions Assumptions
- Pure unit conversion for electric charge using SI prefixes; no physics formulas (e.g., Q = C·V) are applied.
- µ denotes micro (10⁻⁶), m = milli (10⁻³), k = kilo (10³), n = nano (10⁻⁹), and p = pico (10⁻¹²).
- Outputs are rounded to 6 decimal places, using scientific notation for very large/small values.
- Based on SI definitions: 1 C = 1 A·s; only unit scaling is performed.
When to Use This Calculator
- Converting charge measurements from lab instruments between C, mC, µC, nC, and pC.
- Interpreting datasheets and test reports that list charge in different SI-scaled units.
- Moving between capacitor charge quantities commonly expressed in µC and circuit calculations expressed in C.
Input Definitions
- Coulombs — enter a value and choose C, mC, or kC.
- Microcoulombs — enter a value and choose µC, nC, or pC.
- Conversions — µC = C × 10⁶ and C = µC × 10⁻⁶; similarly, mC = C × 10³, nC = C × 10⁹, pC = C × 10¹².
C to Micro C Formula
The following formulas convert coulombs (C) to microcoulombs (µC) and back.
\mu\mathrm{C} = 10^{6}\,\mathrm{C}\mathrm{C} = \frac{\mu\mathrm{C}}{10^{6}}- 1 C = 106 µC.
- 1 mC = 10-3 C.
- 1 kC = 103 C.
- 1 nC = 10-9 C.
- 1 pC = 10-12 C.
How do you convert C to µC? Multiply the value in coulombs by 106 (one million) to get microcoulombs.
How do you convert µC to C? Divide the value in microcoulombs by 106, or multiply by 10-6, to get coulombs.

Example Problem
Convert 0.007 C to microcoulombs (µC).
Use the formula: µC = C × 106.
µC = 0.007 × 106 = 7000 µC
