Coulomb per meter quick reference
| Coulomb per meter | Coulomb per centimeter |
|---|---|
| 1 C/m | = 0.01 C/cm |
| 10 C/m | = 0.1 C/cm |
| 100 C/m | = 1 C/cm |
| 1000 C/m | = 10 C/cm |
Among the 7 linear charge density units on this page, the smallest is the microcoulomb per meter (µC/m) and the largest is the abcoulomb per centimeter (abC/cm).

About linear charge density units
Linear charge density is the electric charge per unit length along a line, such as a charged wire, rod or particle beam. Its SI unit is the coulomb per meter (C/m).
Physics problems often model a long charged wire as a line of charge with density λ. Converting between metric lengths is exact: 1 C/cm is 100 C/m and 1 C/mm is 1000 C/m. One coulomb per inch is about 39.37 C/m.
Frequently asked questions
- What symbol is used for linear charge density?
- Usually the Greek letter λ (lambda). Surface charge density is usually σ and volume charge density ρ.
- How many C/m is 1 C/cm?
- Exactly 100 C/m, because one meter contains 100 centimeters.
- How many coulombs per centimeter are in one coulomb per meter?
- One coulomb per meter = 0.01 C/cm (coulombs per centimeter).
