Conversion From Inches To Gauge In Sheet Metal

Sheet metal gauge conversions.

Conversion from inches to gauge in sheet metal.

The gauge number 18 holds no relevance to the actual measurements. The smaller the number the thicker the material. Is different from inches there is no conversion formula. The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size.

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. Sheet metal gauges work opposite to what one might consider the norm. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

For example 20 gauge mild steel is 036 thick. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. Sheet metal gage conversion chart inches american wire gage sizes. Converting sheet metal gauge to thickness in inches.

Awg decimal size. Working with sheet metal as shown in figure 1 gauge sizes can be confusing at the best of times. You can find the gauge to mm inch conversion for sheet metal by the chart below. Even when the non ferrous metal plate and the steel plate are the same ga the thickness is actually different.

So a 20 gauge brake has a maximum bending capacity of 036. Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5. The thickness of sheet metals is specified by gauge.
