Abcoulomb per Centimeter (abC/cm)
Definition: A CGS-consistent linear charge density unit combining the abcoulomb with the centimeter — the natural length scale of the CGS (centimeter-gram-second) system the abcoulomb itself belongs to.
History: It emerged as the fully CGS-native version of linear charge density, pairing the CGS-EMU charge unit with the CGS system's own base length unit rather than mixing in the SI meter.
Current use: Appears in historical CGS-based electromagnetism literature and calculations that keep every quantity consistently within the centimeter-gram-second unit family.
Abcoulomb per Meter (abC/m)
Definition: A linear charge density unit built from the abcoulomb, the CGS-EMU system's unit of charge, expressed per meter of length — combining an older CGS charge unit with the modern SI meter.
History: It follows from the abcoulomb's fixed 10-coulomb relationship to the SI coulomb, carried through into a per-meter charge density figure for use alongside the rest of the CGS-EMU electromagnetic unit family.
Current use: Encountered mainly when converting older CGS-based electromagnetism texts and calculations into more familiar SI-scaled figures.

About These Parameters
- Value
- The linear charge density value you want to convert, expressed in the "From" unit. Accepts decimals, and can represent anything from a lightly charged laboratory wire to a densely charged conductor in a field-theory problem.
- From Unit
- The unit your input value is currently measured in — a modern coulomb-per-meter (or per-centimeter) figure, or an older CGS-based abcoulomb-per-length figure from legacy electromagnetism literature.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly, which is handy when moving between metric and CGS charge-per-length conventions.
How Linear Charge Density Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the coulomb per meter. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Abcoulomb per Centimeter → Abcoulomb per Meter: multiply by 100. For example, 1 abC/cm × 100 = 100 abC/m.
Why Charge Per Length, Not Just Total Charge?
A charged wire's total charge alone doesn't tell you how strong its electric field is at a given distance — a short, densely charged wire and a long, lightly charged wire can carry the same total charge but produce very different fields nearby. Linear charge density solves this by normalizing charge to the length it's spread across, so the same density figure describes the field-generating behavior of the conductor regardless of how long a section you happen to be looking at. That's why it appears directly in the standard formula for the electric field near an infinite charged line, E = λ / (2πε₀r), where λ is the linear charge density.
Metric vs. CGS Charge-Per-Length Units
The coulomb-per-meter family follows directly from the SI coulomb and meter, while the abcoulomb-per-length family is built from the CGS-EMU system's abcoulomb (10 coulombs) paired with centimeter-, meter-, or inch-scale lengths. Because the CGS system predates SI's international standardization, older transmission-line and electromagnetism texts sometimes express charge density in abcoulombs per centimeter rather than coulombs per meter — this converter bridges both conventions directly.
Example
A linear charge density of 1 abC/cm equals 100 abC/m. For scale, laboratory electrostatics demonstrations with charged rods typically involve linear charge densities on the order of nanocoulombs to microcoulombs per meter, far below the charge densities that would cause visible corona discharge in air.
Frequently Asked Questions
How many Abcoulombs per Meter are in 1 Abcoulomb per Centimeter?
1 Abcoulomb per Centimeter (abC/cm) equals exactly 100 Abcoulombs per Meter (abC/m).
What's the difference between linear charge density and total charge?
Total charge (measured in coulombs) is a single number describing how much charge an object carries overall. Linear charge density (measured in coulombs per meter) describes how that charge is spread along the object's length, which is what actually determines the electric field strength near a long, thin charged conductor.
Why does abcoulomb per meter equal 10 coulombs per meter?
Because the abcoulomb itself is defined as exactly 10 coulombs within the CGS electromagnetic (EMU) unit system, and pairing it with the same SI meter used elsewhere on this page simply carries that fixed 10x relationship straight through into the charge-density unit.
Where does linear charge density actually get used?
It's central to electrostatics problems involving long, thin charged conductors — charged rods, wires, and transmission lines — where the electric field formula depends directly on charge per unit length rather than on the object's total charge. It also appears in some high-voltage transmission-line corona-discharge calculations.
