Frequently Asked Questions
-
What is the EMU of resistance?
-
The EMU of resistance, also called the abohm, is an electrical resistance unit in the electromagnetic CGS system equal to one nanohm (10⁻⁹ ohm).
-
How does the microhm unit relate to the ohm?
-
A microhm is one millionth of an ohm (1 µΩ = 10⁻⁶ ohm), commonly used to measure very low resistances.
-
Why convert EMU of resistance to microhm?
-
Conversion helps relate historical CGS-EMU resistance measurements to modern SI-based units used in precision electrical measurements and research.
-
Can I trust the conversion accuracy using this tool?
-
The tool uses the exact conversion rate of 1 EMU of resistance = 0.001 microhm, but measurement precision depends on instrument quality and conditions.
