What Is This Tool?
This converter tool helps translate values of electrical resistance from statohm, an outdated unit from the electrostatic CGS system, into microhm, a unit representing extremely small resistances in the SI system. It is especially useful for interpreting historical data or theoretical research involving CGS units and expressing results in practical units relevant to precision electrical measurements.
How to Use This Tool?
-
Enter the electrical resistance value in statohms.
-
Select 'statohm' as the input unit and 'microhm' as the output unit.
-
Click convert to see the corresponding resistance in microohms.
-
Use the result to compare, analyze, or apply resistance values in modern contexts.

Frequently Asked Questions
-
What is a statohm?
-
A statohm is the unit of electrical resistance from the electrostatic variant of the CGS system, now obsolete and mainly used in theoretical or historical electromagnetic contexts.
-
Why convert statohms to microohms?
-
Converting statohms to microohms translates old CGS resistance values into practical units used in modern electrical engineering and scientific measurements.
-
Where are microohms commonly used?
-
Microohms are used for measuring very low resistances such as contact resistances, precision shunts, and residual resistance in superconductors.
Key Terminology
-
Statohm
