Microcoulomb to Coulomb (µC to C) Converter
Microcoulomb to coulomb converts a small electric charge by multiplying the microcoulombs by 10⁻⁶, because one microcoulomb is one millionth of a coulomb. Type µC or C in either box and the other updates at once, with the formula shown, and a table lists common values from 1 µC to 1 000 000 µC.
Microcoulombs to coulombs
250 µC = 2.5×10-4 C
C = µC × 10-6 → 250 × 10-6 = 2.5×10-4 C.
How to convert microcoulombs to coulombs
The prefix “micro” means one millionth (BIPM, The International System of Units, 9th edition, 2019), so 1 µC = 0.000001 C = 1×10-6 C. Multiply microcoulombs by 10-6, which moves the decimal point six places to the left. To go back, multiply coulombs by 1 000 000.
Worked example: 250 µC
250 × 10-6 = 0.00025 C, or 2.5×10-4 C.
Worked example: 0.0003 C in microcoulombs
0.0003 × 1 000 000 = 300 µC.

What is a coulomb?
The coulomb is the SI unit of electric charge, defined as one ampere-second (BIPM, 2019). The elementary charge is exactly 1.602176634×10-19 C, so one microcoulomb is about 6.24×1012 elementary charges. Static shocks involve microcoulombs; lightning strikes move tens of coulombs.
