Hello All,

Being new to the world of sheet metal gauges I needed the ability to quickly convert gauges of sheet metal used in international YouTube clips to the Australian market's terminology. I just came across a Chinese-based company who have a website which converts Galvanised Steel, Stainless Steel, Aluminium Sheet Gauge Size to mm / inch Thickness via their Conversion Chart.

The company is Heng Ze Steel and the link to their webpage; where you can also handily download a PDF file version of the conversion chart, was accessed 12th March 2021 from, Sheet Metal Gauge Thickness Chart (to mm/inch Conversions) - Hengze Steel

Hopefully, the conversions are accurate? If so I trust that it will be a handy resource for other people who are equally new to sheet metal for automotive panel repairs and fabrication.

Kind regards
Lionel
