What Is This Tool?
This unit converter allows users to convert electrical resistance values from volt per ampere (V/A), the SI derived unit equal to one ohm, to megohms, a unit measuring one million ohms. This conversion is especially useful for representing high resistance values in electrical engineering applications.
How to Use This Tool?
-
Enter the value in volt/ampere (V/A) that you want to convert
-
Select the target unit as megohm for the conversion
-
Click the convert button to get the equivalent resistance in megohms

Tips & Best Practices
-
Ensure that the resistance values are linear for accurate conversions
-
Use this converter primarily for higher resistance values to benefit from megohm units
-
Verify measurement instrument resolution when converting very low resistances
-
Apply this tool during circuit analysis following Ohm's law relationships
Limitations
-
Conversion assumes resistance values are linear and may not apply for nonlinear or frequency-dependent resistances
-
Accuracy may be affected when converting very low resistance values due to instrument resolution limits
Frequently Asked Questions
-
What does 1 volt per ampere represent in electrical resistance?
-
1 volt per ampere (V/A) is the SI derived unit of electrical resistance equal to one ohm, representing the potential difference needed to drive one ampere of current.
-
Why convert from volt/ampere to megohm?
-
Converting to megohm is useful for expressing very high resistance values, such as insulation resistance or leakage current, more conveniently and clearly.
-
Can this converter be used for nonlinear resistance values?
-
No, this conversion tool is intended for linear resistance values and is less applicable to nonlinear or frequency-dependent resistances.
