What Is This Tool?
This converter enables the transformation of electric potential values measured in EMU of electric potential (abvolt) into ESU of electric potential (statvolt). It helps relate two different centimetre–gram–second (cgs) unit systems — electromagnetic and electrostatic — commonly used in physics and engineering disciplines.
How to Use This Tool?
-
Enter the electric potential value in EMU of electric potential (abvolts).
-
Select the output unit as ESU of electric potential (statvolts).
-
Click the convert button to obtain the corresponding value in ESU units.
-
Review the converted result for your analysis or documentation purposes.

Examples
-
1 EMU of electric potential equals 3.335640484669e-11 ESU of electric potential
-
10 EMU of electric potential equals 3.335640484669e-10 ESU of electric potential
Common Use Cases
-
Interpreting historical laboratory notes and scientific literature using cgs-emu units
-
Relating legacy electromagnetic measurements to electrostatic units for comparison
-
Working on theoretical electrodynamics, magnetostatics, or astrophysics research involving Gaussian units
-
Converting older experimental data expressed in EMU units to ESU for modern analysis
Tips & Best Practices
-
Verify the context of your data to ensure the correct cgs unit system is used
-
Use this tool for theoretical or legacy data since SI units are prevailing in modern measurements
-
Keep in mind the very small conversion factor and use appropriate precision in calculations
-
Cross-check converted values against known standards when possible
Limitations
-
The tool converts between two distinct cgs unit systems that differ conceptually from each other and from SI units
-
The conversion factor is extremely small, requiring careful numerical handling
-
The EMU and ESU unit systems are mostly replaced by SI units in contemporary practice
-
Interpretations across systems should be done cautiously due to differing theoretical bases
Frequently Asked Questions
-
What is the EMU of electric potential?
-
It is the unit of electric potential in the cgs electromagnetic system, known as the abvolt, representing electric potential difference or electromotive force.
-
What does ESU of electric potential measure?
-
It measures electric potential in the cgs electrostatic system, called the statvolt, defined by the potential difference producing one erg of work per statcoulomb.
-
Why convert between EMU and ESU units?
-
Converting helps relate electromagnetic and electrostatic cgs measurements, useful for interpreting historical data and theoretical physics results.
