What Is This Tool?
This tool converts electric resistance measurements from the ohm, the SI unit, to the abohm, the CGS electromagnetic unit. It helps interpret and compare very small resistance values, especially those found in historical electromagnetism literature.
How to Use This Tool?
-
Enter the electric resistance value in ohms
-
Select ohm as the input unit and abohm as the output unit
-
Click the convert button to see the equivalent value in abohms
-
Use the results to interpret or compare very small resistance measurements

Examples
-
2 ohms converts to 2,000,000,000 abohms
-
0.5 ohm converts to 500,000,000 abohms
Common Use Cases
-
Specifying and converting resistor values in electronic circuits
-
Measuring and verifying conductor and contact resistance
-
Interpreting resistance values from historical CGS electromagnetic literature
-
Comparing very small resistance values on the nanohm scale
Tips & Best Practices
-
Ensure correct input units before converting
-
Use this converter primarily for very small resistance values
-
Refer to historical CGS sources when dealing with abohm units
-
Be cautious with precision when interpreting nanohm-level resistance
Limitations
-
Abohm is rarely used in current engineering due to its extremely small scale
-
Measurement noise and instrument precision limit practical use at the nanohm level
Frequently Asked Questions
-
What is the ohm unit used for?
-
The ohm is the SI derived unit of electrical resistance and quantifies how much a component resists electric current. It is commonly used to specify resistor values and measure conductor resistance.
-
Why convert ohms to abohms?
-
Conversion to abohms is useful for interpreting very small resistance values in historical CGS electromagnetism data or expressing resistance on the nanohm scale.
-
Is the abohm commonly used today?
-
No, the abohm is rarely used in modern engineering because of its extremely small size and the challenges of precise measurement at that scale.
Key Terminology
-
Ohm
-
The SI derived unit of electrical resistance defining opposition to current flow based on volts and amperes.
-
Abohm
-
The unit of electrical resistance in the CGS electromagnetic system equal to one nanohm in SI units.
-
Electrical Resistance
-
A measure of the opposition a material or component presents to the flow of electric current.
