How to Convert SWG to MM (Step-by-Step)
SWG values do not follow a simple formula. You must use a standard conversion table.
Step-by-Step Method
- Identify the SWG number
- Find the corresponding diameter from a standard chart
- Read the value in millimeters
Example Calculation
Convert SWG 16 to mm:
Step 2: Look up SWG 16 in the conversion chart
Step 3: Find the diameter
Result: SWG 16 = 1.626 mm
Final Answer: 1.626 mm
