This chart covers the common and uncommon sheet metal sizes for steel aluminum and galvanized steel.
Aluminum sheet gauge conversion.
Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.
Sheet metal gauge conversions.
Sheet metal gauge to mm.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.
You can find the gauge to mm inch conversion for sheet metal by the chart below.
For a more comprehensive gauge chart you can check out our sheet metal gauge chart here.
For example we determined that 20 gauge mild steel was 036 thick so multiply 036 by 1 5 036 x 1 5.
According to the chart provided above a 20 gauge brake will also bend 16 gauge aluminum but not quite 15 gauge because 054 falls between 051 which is 16 gauge aluminum and 057 which is 15 gauge aluminum.
Is different from inches there is no conversion formula.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Steel galvanized and aluminum.
The gauge number 18 holds no relevance to the actual measurements.
There are several different gauge systems used today with specific gauge designations used for specific metal types.

Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.
