What Is This Tool?
This converter transforms electric current values measured in CGS electrostatic units (statamperes) into electromagnetic units (abamperes or EMU of current). It is useful for reconciling different CGS subsystem units used across historical, theoretical, and experimental physics.
How to Use This Tool?
-
Enter the numeric current value in CGS e.s. units (statamperes)
-
Select the input unit as CGS e.s. unit (electrostatic system)
-
Choose the output unit as EMU of current (electromagnetic system)
-
Click the convert button to obtain the equivalent current in EMU
-
View the converted value and utilize it for your calculations or data comparison
Key Features

Examples
-
1 CGS e.s. unit equals approximately 3.335641×10⁻¹¹ EMU of current
-
10 CGS e.s. units convert to about 3.335641×10⁻¹⁰ EMU of current
Common Use Cases
-
Reporting currents in older research using Gaussian or CGS-ESU units
-
Converting historical electrodynamics results into modern electromagnetic units
-
Analyzing plasma physics experiments referencing different CGS subsystem units
-
Translating magnetic moment measurements in materials science and geophysics
-
Reconciling legacy data for engineering or instrumentation requiring SI compatibility
Tips & Best Practices
-
Verify the unit system context before conversion to avoid confusion between ESU and EMU
-
Use this tool primarily for research or analysis involving classical CGS units
-
Be mindful of floating-point precision when dealing with very small conversion values
-
Cross-check converted values when working with sensitive experimental data
-
Remember modern electronics usually employ SI units, so conversions might not be necessary
Limitations
-
ESU and EMU are different CGS subsystems; conversions should be applied carefully
-
Numerical results involve very small values, risking floating-point precision issues
-
These units are rarely used in modern engineering or electronics contexts
Frequently Asked Questions
-
What does CGS e.s. unit of current represent?
-
It is the electrostatic unit of electric current in the CGS electrostatic system, corresponding to one statcoulomb flowing per second.
-
How is EMU of current defined?
-
EMU of current is the electromagnetic unit of current in the CGS-EMU system, equivalent to the abampere and equal to 10 amperes in SI units.
