Examples
| 1 C | 1000000000000 pC |
| 5 C | 5000000000000 pC |
| 10 C | 10000000000000 pC |
| 100 C | 100000000000000 pC |
One coulomb equals 1.0000e+12 picocoulombs (pC). To convert coulombs to picocoulombs, multiply by 1.0000e+12; to go back the other way, multiply by 1.0000e-12 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 coulombs and picocoulombs actually measure
Coulomb (C) — The coulomb is the SI unit of charge — one amp flowing for one second. Physics and electrical theory.
Picocoulomb (pC) — A picocoulomb is a trillionth of a coulomb. Piezoelectric sensors and electrometry.

How to convert coulombs to picocoulombs by hand
Multiply the number of coulombs by 1.0000e+12.
For example, 25 C × 1.0000e+12 = 2.5000e+13 pC.
Going the other way, divide by 1.0000e+12 — or multiply by 1.0000e-12, 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.
Questions people ask
How many pC are in 1 C?
1 C equals exactly 1000000000000 pC. Multiply any value in coulomb by 1000000000000 to get picocoulomb.
Is anything uploaded to a server?
No. The whole calculation happens in your browser. Nothing is sent anywhere, and the page keeps working offline once loaded.
