With a micrometer.
Usually in terms of gauge, 22 ga steel is .0299 in thick, the actual thickness for different materials
varies aluminum of the same gauge is somewhat thinner than steel, galvanized steel is a little thicker than plain steel of the same gauge. A micrometer is one way to measure it, there are gauge plates that have slots for each size.
Sheet metal thickness can be determined by measuring it. Several specialty tools are available to tell how thing the sheet metal is in actual measurement or by guage, a form of measurement that is used for various types of sheet metal thickness.
Measure the thickness of multiple sheets (Say, ten or twenty) then divide the answer by the number of sheets to get the thickness of a single sheet.
ON the cad offset the bend radius from the internal radius of the sheet metal part by 40% of the total sheet thickness,and measure the chord length of the radius. that will be the developed length.

Sheet thickness gauges are tools used to measure the thickness of materials, typically metal sheets or foils. They consist of a calibrated instrument with a mechanism to determine the thickness by pressing the material between two anvils or rollers. These gauges ensure accuracy in material thickness measurements for quality control and compliance with specifications.
If it is steel, the thickness is 0.0359 ins (35.9 thou), or 0.9119 mm. See Wikipedia 'Sheet Metal Gauge' for a full table of thicknesses

To measure the average thickness of a single sheet in a 500-page textbook, you can first measure the total thickness of the book using a caliper or ruler. Then, divide this total thickness by the number of sheets, which is typically half the number of pages (250 sheets for a 500-page book, assuming each sheet has two pages). This calculation will provide the average thickness of a single sheet.
The easiest way to measure the thickness of a sheet of paper is to use a ruler or caliper. Simply place the paper on a flat surface, use the ruler or caliper to measure the thickness of the paper, and record the measurement in millimeters or inches.
A micrometer is commonly used to measure the thickness of nonferrous sheet metal. It provides precise measurements by utilizing a calibrated screw mechanism. Other tools like calipers and gauge blocks can also be used for this purpose.
The blank size of sheet metal can be calculated using the bend allowance. This number is based on the metal thickness and the tool radius in the brake.
