There are several different gauge systems used today with specific gauge designations used for specific metal types.
Sheet metal gauge thickness inches.

The gauge number 18 holds no relevance to the actual measurements.
For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18.
The corresponding galvanized steel thickness is 0 0366 inches 0 93mm and the corresponding aluminum thickness is 0 028 inches 0 71mm.
The table below provides conversion to inches.
The smaller the number the thicker the material.
Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.
For other materials such as aluminum and brass the thicknesses will be different.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
Hence 4 gauge material is thicker than 6 gauge material.
Converting sheet metal gauge to thickness in inches.
Corresponds to the standard steel thickness of 0 0329 inches 0 84mm.
Gague are used to specify the thickness of a metal sheet.
Gauge to thickness chart.
Sheet metal gauges work opposite to what one might consider the norm.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material.
Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh 41 82 0 1345 5 625 pounds per square foot.
16 ga crs is 2 5 pounds per square foot.
Metal sheet thickness is measured in gauge.
Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times.
