What Is This Tool?
This online converter allows you to change inductance values from the EMU (electromagnetic unit) of inductance system, historically known as the abhenry, to the ESU (electrostatic unit) of inductance system. It helps interpret and compare these classical cgs subsystem units used mainly in historical and theoretical electromagnetic contexts.

Examples
-
1 EMU of inductance = 1.11265002973e-21 ESU of inductance
-
5 EMU of inductance = 5.56325014865e-21 ESU of inductance
Common Use Cases
-
Interpreting electromagnetic data from historical cgs-EMU and cgs-ESU literature.
-
Converting archival measurements for use in modern SI units in physics research.
-
Educational purposes comparing classical unit systems in advanced physics or metrology.
-
Analyzing small inductance values such as nanohenry-range coils in historical contexts.
Tips & Best Practices
-
Ensure accurate numeric input due to the very small conversion factor involved.
-
Use the conversion primarily for historical, theoretical, or educational analyses.
-
Cross-check converted values when applying to sensitive scientific calculations.
-
Understand the context of legacy measurement systems before comparing with modern units.
Limitations
-
The conversion factor between EMU and ESU inductance is extremely small requiring careful numerical precision.
-
Both units are mostly obsolete and relevant only in theoretical or historical electromagnetic contexts.
-
Not intended for practical modern applications where SI units like henry are standard.
Frequently Asked Questions
-
What is EMU of inductance?
-
EMU of inductance is an old cgs-EMU unit called the abhenry, representing magnetic flux linkage per unit current and equal to 10⁻⁹ henry in SI units.
-
When would I need to convert EMU of inductance to ESU of inductance?
-
This conversion is useful when interpreting historical electromagnetic measurements or in educational settings comparing classical unit systems.
-
Is this conversion relevant for modern engineering?
-
No, these units are mostly obsolete and are used mainly for theoretical, historical, or archival scientific research rather than modern practical engineering.
Key Terminology

EMU of Inductance
-
A unit of inductance in the cgs-EMU system known as the abhenry, equal to 10⁻⁹ henry in SI.
-
ESU of Inductance
-
A unit of inductance in the cgs-ESU system used historically to quantify electromotive force response to current changes.
-
Inductance
-
A measure of a circuit element’s ability to induce an electromotive force due to changes in current.
