Linear Current Density formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in A/m.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (A/m) |
Linear Current Density examples
A/m to A/cm
10 A/m = 0.1 A/cm.
A/m to A/mm
10 A/m = 0.01 A/mm.
A/cm to A/m
10 A/cm = 1,000 A/m.
How to calculate Linear Current Density step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Linear Current Density result
Linear current density is current per unit length across a sheet or surface. The SI unit is ampere per metre. One A/cm is 100 A/m and one A/mm is 1,000 A/m.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 A/M |
|---|---|---|---|
| Ampere per meter | A/m | 1 A/m = 1 A/m | 1 A/m |
| Ampere per centimeter | A/cm | 1 A/cm = 100 A/m | 0.01 A/cm |
| Ampere per millimeter | A/mm | 1 A/mm = 1,000 A/m | 0.001 A/mm |
| Ampere per inch | A/in | 1 A/in = 39.370079 A/m | 0.0254 A/in |
| Ampere per foot | A/ft | 1 A/ft = 3.2808399 A/m | 0.3048 A/ft |
Common mistakes when calculating Linear Current Density
- Mixing linear current density (A/m) with surface current density (A/m²).
- Mixing A/cm and A/mm, which differ by 10.
- Confusing it with magnetic field strength, which has the same unit but a different meaning.
Linear Current Density FAQ
How many A/m is 1 A/cm?
1 A/cm is 100 A/m.
How many A/m is 1 A/mm?
1 A/mm is 1,000 A/m.
Is A/m always a current density?
The unit A/m is shared with magnetic field strength, so the context decides which quantity it measures.
What is the base unit for linear current density?
This converter uses ampere per meter (A/m) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two linear current density units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many amperes per centimeter are in 1 ampere per meter?
1 A/m = 0.01 A/cm.
How many amperes per millimeter are in 1 ampere per meter?
1 A/m = 0.001 A/mm.
How many amperes per meter are in 1 ampere per centimeter?
1 A/cm = 100 A/m.
Which linear current density units does this converter support?
It covers 5 units: ampere per meter (A/m), ampere per centimeter (A/cm), ampere per millimeter (A/mm), ampere per inch (A/in), ampere per foot (A/ft).
How accurate is the linear current density converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
