Frequently Asked Questions
-
What is ESU of inductance?
-
The ESU of inductance is a unit from the electrostatic cgs-ESU system used historically to measure inductance in electromagnetic theory.
-
When should I convert ESU of inductance to petahenry?
-
Conversion is useful when interpreting legacy cgs-ESU measurements within a modern SI framework or for large-scale theoretical electromagnetic calculations.
