Convert C to µC (coulombs to microcoulombs) or µC back to C, plus millicoulombs, nanocoulombs and picocoulombs, for positive or negative charges.

µC is micro (often typed uC or mcC) = 0.000001 C; mC is milli = 0.001 C. Negative charge is allowed.

Optional settings

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
  • Electric charge — enter a signed value and choose C, mC, kC, µC, nC, or pC.
  • Result unit — choose the desired charge unit, then select Calculate.
  • Unit identities — 1 C = 10⁶ µC = 10³ mC = 10⁹ nC = 10¹² pC.

C to Micro C Formula

The following formulas convert the numerical charge value q between coulombs (C) and microcoulombs (µC). The subscript names the unit in which q is expressed.

qμC = 10⁶ qC
qC = (qμC) / (10⁶)
  • 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).

Multiply the numerical value in C by 106.

0.007 C = (0.007 × 106) µC = 7000 µC
