If you measure the thickness of a nickel, it will equal 1.95 mm. Although it is just shy of 2 mm it is close enough to use as a reference.

Coins are a great item to use for size references. The Canadian dime is a coin that is worth 10 cents in value. Similar to the nickel coin, the dime is very common and often kept by many people.

If you measure the thickness of a Canadian dime, it will equal 1.22 mm. So if you placed 2 dimes one on top of the other, it will equal just over 2 mm thick. Not exactly but it’s close.

20 sheets of paper

A sheet of paper can vary in dimensions and has several different uses. The thickness of a sheet of printer paper can range from 0.05 to 0.10 mm. 

So if 1 sheet of paper is 0.10 mm thick, 10 sheets will equal 1mm thick and 20 sheets will equal 2 mm thick. 

Placing 20 sheets of paper one on top of each other will show you the size of 2 mm.
