What Is This Tool?
This converter allows you to transform inductance measurements from the historical ESU of inductance unit, used in the electrostatic cgs-ESU system, into the SI derived unit weber per ampere (Wb/A), which is equivalent to the henry. It is designed to assist in interpreting legacy electromagnetic data and bridging classical and modern unit systems.

Frequently Asked Questions
-
What is the ESU of inductance unit?
-
The ESU of inductance is a unit from the electrostatic cgs-ESU system used historically to quantify inductance based on electromotive force generation in response to changing current.
-
How is the weber per ampere unit related to the henry?
-
The weber per ampere (Wb/A) is an SI derived unit of inductance that is identical to the henry, measuring magnetic flux linkage per unit current.
-
Why convert ESU of inductance to weber/ampere?
-
Converting ESU of inductance to weber/ampere helps translate legacy inductance data from the cgs-ESU system into modern SI units for compatibility with contemporary electrical engineering and research methods.
Key Terminology
-
ESU of Inductance
-
A historical inductance unit in the electrostatic cgs-ESU system that measures a circuit's ability to generate electromotive force from current changes.
-
Weber per Ampere (Wb/A)
-
An SI derived unit of inductance reflecting magnetic flux linkage per ampere of current; equivalent to the henry.
-
Inductance
-
A property of a circuit element indicating how it generates an electromotive force in response to a change in current.
