Frequently Asked Questions
- Why convert from ampere per square inch to ampere per square mil?
- Converting is helpful to accurately specify and compare current density in very small surface areas, especially in microelectronic and PCB designs that use mil-based measurements.
- What unit does ampere per square mil correspond to?
- Ampere per square mil measures current per area with surface expressed in square mils, where one mil equals 0.001 inch.
- Are there challenges when using ampere per square mil units?
- Yes, since it involves very small area units, numerical values after conversion can be tiny, requiring careful handling to avoid errors.
