Examples

1 µC	0.000001 C
5 µC	0.000005 C
10 µC	0.00001 C
100 µC	0.0001 C

One microcoulomb equals 1.0000e-6 coulombs (C). To convert microcoulombs to coulombs, multiply by 1.0000e-6; to go back the other way, multiply by 1000000 instead.

The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.

What microcoulombs and coulombs actually measure

Microcoulomb (µC) — A microcoulomb is a millionth of a coulomb. Capacitor charge and laboratory electrostatics.

Coulomb (C) — The coulomb is the SI unit of charge — one amp flowing for one second. Physics and electrical theory.

How to convert microcoulombs to coulombs by hand

Multiply the number of microcoulombs by 1.0000e-6.

For example, 25 µC × 1.0000e-6 = 2.5000e-5 C.

Going the other way, divide by 1.0000e-6 — or multiply by 1000000, which is the same thing and easier to do in your head.

Everything runs in your browser

There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
