How the formula works
Both coulomb and microcoulomb measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in coulombs by 1.000000e+06 to get microcoulombs. To reverse the conversion, multiply a microcoulomb value by 0.000001 to get back to coulombs.
Frequently asked questions
What is Coulomb (C)?
The coulomb (C) is the SI unit of electric charge, equal to the charge carried by a steady current of one ampere flowing for one second.
What is Microcoulomb (uC)?
A Microcoulomb (uC) equals 1e-06 coulomb(s), a scaled unit of electric charge used for micro-scale electrical work.
How do I convert coulombs to microcoulombs?
Multiply the coulomb value by 1.000000e+06 to get the equivalent in microcoulombs. For example, 5 C × 1.000000e+06 = 5.000000e+06 uC.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert microcoulombs back to coulombs?
Yes. Divide the microcoulomb value by 1.000000e+06, or multiply it by 0.000001, to get coulombs.
