What Is This Tool?
This converter allows users to convert electrical resistance values from EMU of resistance, the cgs electromagnetic unit also known as abohm, to megohms, a modern SI unit used for measuring high resistance. It helps translate historical or theoretical resistance values into practical units for engineering and scientific use.
How to Use This Tool?
-
Enter the resistance value in EMU of resistance units
-
Select EMU of resistance as the input unit and megohm as the output unit
-
Click convert to get the corresponding value in megohms
-
Use the result for comparison or engineering calculations
Key Features
-
Converts EMU of resistance (abohm) values to megohms with ease
-
Browser-based and user-friendly interface
-
Supports translation of legacy CGS-EMU data to SI units
-
Useful for high resistance measurement applications and archival data interpretation
Examples
-
5 EMU of resistance = 5 × 1e-15 = 5e-15 megohm
-
1,000 EMU of resistance = 1,000 × 1e-15 = 1e-12 megohm
Common Use Cases
-
Converting resistance values from older CGS–EMU literature to SI ohms
-
Performing electromagnetic theoretical calculations in the CGS system
-
Analyzing historical experimental data published before widespread SI adoption
-
Testing insulation resistance in cables, motors, and transformers using megohm units
-
Specifying leakage or dielectric resistance in materials and capacitors
-
Defining high-value resistor parameters and input impedance for high-impedance instruments
Tips & Best Practices
-
Ensure input values are accurate and based on reliable historical or experimental sources
-
Use this conversion to compare legacy resistance data with modern measurements
-
Account for the extremely small conversion factor when working with EMU of resistance
-
Be mindful of the precision limits due to the large difference in unit scales
Limitations
-
Due to the large difference in scale, converted values are extremely small and require high precision
-
Historical data may have precision or measurement condition issues limiting conversion accuracy
-
The EMU of resistance unit is very small (nanohm scale) whereas megohms are very large resistance units
