This tool does not provide precision adjustments beyond the fundamental conversion factor
Frequently Asked Questions
-
What is an EMU of capacitance?
-
The EMU of capacitance, also called the abfarad, is the unit in the electromagnetic subsystem of the centimetre–gram–second system, representing capacitance as the ratio of charge to voltage according to cgs-emu conventions.
-
Why convert from EMU of capacitance to ESU of capacitance?
-
Conversion helps translate capacitance values between different cgs subsystems, facilitating comparison of theoretical or historical data and aiding interpretation in classical electrodynamics studies.
-
Are these units commonly used in modern engineering?
-
No, EMU and ESU units are mainly of historical and theoretical interest and rarely appear in modern engineering which typically employs SI units.
