What Is This Tool?
This converter transforms linear current density measurements from ampere per centimeter (A/cm), an SI unit, to abampere per inch (abA/in), a CGS-EMU unit. It is designed to help users bridge between modern and legacy unit systems in electrical and electromagnetic fields.
How to Use This Tool?
-
Enter the value in ampere per centimeter [A/cm] that you wish to convert
-
Select ampere/centimeter as the input unit and abampere/inch as the output unit
-
Click the convert button to see the result in abampere per inch [abA/in]
-
Use the result for engineering design, research, or legacy data conversion

Common Use Cases
-
Specifying current per unit width of PCB traces and bus bars for electrical design
-
Characterizing current distribution along electrode edges in electrochemical processes
-
Describing linear current in railgun rails, arc channels, or high-current contacts
-
Interpreting line currents in legacy CGS-EMU magnetostatics literature
-
Converting historical electromagnetic data for modern simulation and engineering
Tips & Best Practices
-
Always verify units before performing conversions to avoid errors
-
Use this tool to ensure compatibility between SI and CGS-EMU systems
-
Refer to the conversion formula 1 A/cm = 0.254 abA/in for manual calculations
-
Be cautious when applying results in sensitive calculations due to unit system differences
Limitations
-
The abampere/inch unit belongs to the outdated CGS electromagnetic system, which is less commonly used today
-
Precision may vary when converting between unit systems if exact definitions are not applied
-
Improper mixing of unit systems without proper conversion may lead to misinterpretation of linear current density
