Frequently Asked Questions
-
What does ampere per square mil measure?
-
It measures surface current density, indicating electric current flowing per unit area expressed in square mils, commonly used in electrical engineering for small-scale imperial-area designs.
-
Why convert to abampere per square centimeter?
-
Converting to abampere per square centimeter allows compatibility with CGS electromagnetic analyses, theoretical studies, and legacy data using CGS units.
-
Is the conversion exact?
-
The conversion uses a precise rate based on defined units, but practical measurements may include tolerances and legacy CGS units may not align with SI-based workflows.
Key Terminology
-
Ampere per square mil [A/mi^2]
-
A surface current density unit indicating electric current per area where the area is measured in square mils (0.001 inch squared), frequently used in inch-based electrical design contexts.
-
Abampere per square centimeter
-
A CGS-EMU electromagnetic unit measuring electric current per square centimeter of surface area, equal to one abampere flowing through one square centimeter.
-
Surface current density
-
A measurement of electric current flow per unit surface area, important in characterizing conductors, films, and plasma currents.
