Calculation Formula

Diameter (inches) = 0.005 in/gauge2 × 92.5 / sqrt(Material Factor)

Where:
- 0.005 in/gauge2 is the basic formula factor
- 92.5 is a constant in the American Wire Gauge system
- Material Factor varies based on wire material

Gauge to Inches Calculator Usage Guide

Learn how to use the Gauge to Inches Calculator and understand wire gauge conversions

How to Use This Calculator

  1. Select the wire gauge number from the dropdown (0-40). Lower numbers indicate thicker wire.
  2. Choose the material type (copper, aluminum, or iron) if applicable.
  3. Click the "Calculate" button to determine the wire diameter.
  4. The calculator displays the diameter in both inches and millimeters, as well as the circular mil value.

Understanding Wire Gauge

Wire gauge is a measurement system for wire diameter. In the American Wire Gauge (AWG) system, a lower gauge number means a thicker wire, while a higher gauge number means a thinner wire. The AWG system was developed to standardize wire sizes for electrical applications.

Why Use This Calculator?

  • Electrical engineers and technicians need to select appropriate wire sizes for their applications.
  • When working with electrical systems, it's important to match wire gauge with amperage capacity.
  • This calculator helps convert between gauge numbers and actual dimensions.
  • Circular mil is a unit of cross-sectional area used in electrical engineering.
