View Sheet Metal Gauge To MM Conversion Formula Here

Thickness Gauge To MM Conversion Formula


Thickness (mm) = (0.254 * (47.8 - Gauge)) / 100

For eg:

  • 16 gauge to mm
  • Thickness (mm) = (0.254 * (47.8 - 16 )) / 100
  • Thickness (mm) = 1.626 mm

SWG to mm : Thick (mm) = 0.127 * (32 - SWG)
SWG to Inches : Thick (inch) : 0.005 * (32 - SWG)

How to Select the Right Gauge in Sheet Metal For Your Projects


Identify Your Application Needs
  • lower gauge for strength
  • higher gauge for flexibility
Cost
  • Thicker gauges : more cost (used for heavy duty)
  • Match gauge no.with thickness
  • Stainless steel: for strength use 16 or 18 gauge
