Coulomb per meter quick reference
| Coulomb per meter | Coulomb per centimeter | Coulomb per millimeter | Microcoulomb per meter |
|---|---|---|---|
| 1 C/m | = 0.01 C/cm | = 0.001 C/mm | = 1000000 µC/m |
| 10 C/m | = 0.1 C/cm | = 0.01 C/mm | = 10000000 µC/m |
| 100 C/m | = 1 C/cm | = 0.1 C/mm | = 100000000 µC/m |
| 1000 C/m | = 10 C/cm | = 1 C/mm | = 1000000000 µC/m |
Where the coulomb per meter fits
The next smaller linear charge density unit is the microcoulomb per meter (µC/m). 1 C/m = 1000000 µC/m, and 1 µC/m = 0.000001 C/m.
The next larger linear charge density unit is the coulomb per foot (C/ft). 1 C/m = 0.3048 C/ft, and 1 C/ft ≈ 3.280839895 C/m.
