What Is This Tool?
This converter transforms electrical resistance values from statohm, a historic electrostatic unit used in the CGS system, into reciprocal siemens, the SI standard unit equivalent to ohms, making it easier to interpret classical electromagnetism data in modern terms.
How to Use This Tool?
-
Enter the electric resistance value in statohms.
-
Select 'statohm' as the input unit and 'reciprocal siemens [1/S]' as the output unit.
-
Start the conversion to receive the equivalent reciprocal siemens value.
Key Features
-
Converts obsolete statohm resistance units to SI reciprocal siemens.
-
Utilizes the fixed conversion factor of 1 statohm = 898755200000 reciprocal siemens.
-
Supports practical and theoretical applications in electromagnetism and electrical engineering.
Examples
-
2 statohm converts to 1,797,510,400,000 reciprocal siemens (2 × 898755200000).
-
0.5 statohm converts to 449,377,600,000 reciprocal siemens (0.5 × 898755200000).
Common Use Cases
-
Translating resistance data from historic CGS-ESU units to modern SI units for engineering comparison.
-
Interpreting classical electromagnetic theory papers that use CGS-ESU unit conventions.
-
Educational contexts highlighting differences between CGS and SI electrical measurements.
Tips & Best Practices
-
Carefully handle large numerical values due to the high conversion factor to avoid computation errors.

Not intended for everyday practical electrical measurements.
Frequently Asked Questions
-
What is a statohm?
-
A statohm is a historical unit of electrical resistance from the electrostatic CGS-ESU system, mostly used in theoretical electromagnetism and now considered obsolete.
-
What does reciprocal siemens measure?
-
Reciprocal siemens (1/S) measures electrical resistance, equivalent to ohms in the SI system, representing opposition to electric current.
-
Why convert statohm to reciprocal siemens?
-
Converting statohm to reciprocal siemens helps translate historical or theoretical resistance values into the modern SI framework for practical engineering comparisons and academic study.
