Feeler gauges consist of thin slivers of metal which are graduated in thickness, probably from 0.003 ins up to 0.030 ins (ie 3 thou to 30 thou). This is assuming they are calibrated in inches, or they could be in mm. 3 thou would be about 0.075 mm and 30 thou would be 0.75 mm. You just find the appropriate thickness for the gap you have. Start with one thinner than the gap and work up until you find the one that just fits. Don't force the gap by trying to put in one that is too thick.
Engine assembly, checking valve lash, spark plug gap etc
feeler gauge sets can be conbined to make thickness within their range, try any tool/hardware store.
A paint thickness gauge will allow you to find out the thickness of the paint you are using. This means that when this is necessary for particular tasks that you have a good tool to help you.
Functional gauge is any type of gauge that can be used to verify a part or feature of a part will fulfill its function. Their purpose is to receive a pass/fail result of whether a specific feature on a part will meet its function.
A strain gauge is used to measure the strain of an object. It was invented by the inventors Edward Simmons and Arthur Ruge in 1938. There are several types of gauges (metallic, capacitance, photo-electrics and semiconductor gauges).
18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.

A feeler gauge is actually a set of very fine strips of steel used to measure small gaps such as plug gap of an auto plug, or gaps in bearing surfaces.
The first generation of electronic ignition systems had a requirement to set the air gap between the reluctor and the pickup. It had to be set with a non ferrous metal gauge. That is why the brass blade in a feeler gauge set.

Adjusting the valves on a Caterpillar C 15 Engine is easy and does not take long at all. All you need is a wrench and a feeler gauge, You will then loosen up the bolt, place the feeler gauge in between the rocker arm and valve and then turn the wrench until the rocker arm touches the feeler gauge.
When was the last time you changed your spark plugs and wires? DO NOT USE A FEELER GAUGE ON THE PLUGS... THEY ARE PRESET AT THE FACTORY AND A FEELER GAUGE OR GAPPING TOOL WILL RUIN THE PLATINUM COATING.
By the use of feeler gauge and with dial indicator as possible.
