Its Wire Gauge Calculator includes AWG-based diameter conversion in both inches and millimeters, plus cross-sectional area and resistance outputs. The page explains the AWG formulas and provides reference values, making it useful for both quick conversion and verification.
This AWG chart includes a row for 2 AWG with diameter, cross‑sectional area, resistance, and ampacity. It serves as a detailed lookup for #2 gauge wire data. ([electricaltechnology.org](https://www.electricaltechnology.org/2022/04/american-wire-gauge-awg-chart-wire-size-ampacity-table.html))
The skin depth calculator allows you to determine the skin effect in conductors for any signal frequency.
