Linear Current Density units
Every unit below converts to every other one in the calculator. Values are relative to the base unit, the ampere per meter (A/m).
| Unit | Symbol | System | Value |
|---|---|---|---|
| Ampere per centimeter | A/cm | SI | = 100 A/m |
| Ampere per millimeter | A/mm | SI | = 1000 A/m |
| Ampere per inch | A/in | US customary | ≈ 39.37007874 A/m |
| Ampere per foot | A/ft | US customary | ≈ 3.280839895 A/m |
| Abampere per centimeter | abA/cm | CGS | = 1000 A/m |
| Ampere per meter | A/m | SI | Base unit |
| Kiloampere per meter | kA/m | SI | = 1000 A/m |
Ampere per meter quick reference
| Ampere per meter | Ampere per centimeter |
|---|---|
| 1 A/m | = 0.01 A/cm |
| 10 A/m | = 0.1 A/cm |
| 100 A/m | = 1 A/cm |
| 1000 A/m | = 10 A/cm |
Among the 7 linear current density units on this page, the smallest is the ampere per meter (A/m) and the largest is the kiloampere per meter (kA/m).

About linear current density units
Linear current density is current per unit width, such as the current flowing in a thin conducting sheet or along the surface of a conductor. Its SI unit is the ampere per meter (A/m).
The ampere per meter is also the SI unit of magnetic field strength (H), so the same numbers appear in magnetics. Metric conversions are exact: 1 A/cm is 100 A/m and 1 A/mm is 1000 A/m.
Frequently asked questions
- How many A/m is 1 A/cm?
- Exactly 100 A/m.
- Is linear current density the same as current density?
- No. Current density usually means current per area (A/m²) through a cross-section. Linear current density is current per width (A/m) along a sheet or surface.
- How many amperes per centimeter are in one ampere per meter?
- One ampere per meter = 0.01 A/cm (amperes per centimeter).
