Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times.
Copper sheet conversion inches to gauge.
As with steel as the gauge gets higher the thickness gets lower.
The smaller the number the thicker the material.
Sheet metal gauges work opposite to what one might consider the norm.
Is different from inches there is no conversion formula.
These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.
Hence 4 gauge material is thicker than 6 gauge material.
Below is a quick guide to help you determine which thickness best suits the needs of your project.
Periodic table of elements.
Copper sheeting comes in thicknesses ranging from very thin copper foil to thick copper plate.
There are several different gauge systems used today.

The thickness of sheet metals is specified by gauge.
You can find the gauge to mm inch conversion for sheet metal by the chart below.
It s based on the american or brown and sharpe wire gauge standard.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Unlike with steel i can t find a set.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Gauge when applied to copper brass or silver means a different set of thicknesses however.
In an earlier article we took a look at the standard gauges for steel sheet.
The gauge number 18 holds no relevance to the actual measurements.
Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
Conveniently determine the diameter in inches or millimeters of wire gauges from 10 to 38 gauge.
The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.
