If you are a fan of measuring staff and learning about the dimensions of stuff, then you understand how hectic it is. You might have to whip out your ruler or calipers if you see something interesting to measure. You will always carry suppliers in your backpack to keep your hobby interesting.
However, even if you spend 100 years measuring stuff, you will probably not cover everything. But it is nothing to stress about because the internet sometimes provides the information you cannot find anywhere else. The millimeter unit is used to find the size of small items.
In size, 1 mm is tiny, and only a few items fall under this category. Therefore, if you want to know about items 1 mm thick, read this.
1. 10 Sheets of Paper
The standard size of a sheet of paper should be 8.5 x 11 inches. This paper is also 0.004 inches thick (0.1 mm). Therefore, if you have 10 sheets of paper, you will have a thickness of 1 millimeter.
If you add 90 more sheets, you will have 10 mm (0.40 inches. This applies to regular writing papers and not art papers.
2. Credit/Debit Card
Plastic cards, including credit and debit cards, fall under the ID-1 category and must follow specific size specifications. They are 85.6 mm x 53.98 mm and around 0.76 mm thick.
This thickness might be 0.24 mm less than 1 mm, but it still works. Some cards, however, reach up to 1 mm.
3. Cake Knife Blade
Cake knives are better than chef’s knives for cutting a cake. They make better slices without frosting smears. These knives have a tapering blade that can be 7-15 inches long.
Considering these knives can make clear cuts, they are around 1 mm thick. Cake and pie servers may also be 1 mm thick, but they are designed differently.
4. Graphite Pencil Tip
Most pencils use graphite and lead inside a wooden shaft to write. These graphite pencils are used for drawing, sketching, and stenography notes. The thickness of the pencils may also differ depending on the grade.
Finer pencils have a tip thickness of around 1 mm, but thicker ones can reach up to 2 millimeters.
5. Plastic Id Card
PVC Id cards last longer and can easily be stored in the wallet or pocket. Even though they must meet specific printing needs, they are still better.
Plastic ID cards also have unique size requirements, most of which are uniform. A standard plastic Id is around 1 millimeter thick.
6. Lace Weight Yarn
The lace weight yarn is the thinnest yarn weight for producing fine gauge, light, and airy fabric. It is specifically used to make shawls, wraps, and delicate projects.
In addition, lace weight yarns are knitted or crocheted on larger needles and hooks to create lacy patterns. Lace yarns can be as thin as 1 mm, with the thickest yarn being around 12.75 mm at least.
7. 10 Strands of Hair
The thickness of hair is determined by measuring the diameter. By standards, thin hair has a diameter of around 0.004 to 0.06 mm. Thick hair is around 0.08 and 0.1 mm.
Therefore, if you have 10 strands of thick hair, you will get an overall thickness of 1 millimeter.
8. Medium Ballpoint Tip
The tip of a ballpoint pen is what defines the pen. The tip has a freely rotating ball held inside a small socket that connects it to an ink reservoir that enables writing on paper.
Ballpoint pens have various tip sizes; the most used is the medium and fine sizes. The medium tip is 1 mm thick, while the fine tip is 0.7 mm.
9. Screen Protectors
Many people use smartphones for almost everything, and it is vital to keep them in good shape. The best way to keep your screen in good condition for a long time is to use a screen protector to prevent cracking if it drops.
Screen protectors can either be glass or plastic with varying thickness grades. For example, a glass screen protector can be around 0.5-1mm thick, while plastic protectors can reach around 0.1-0.3 mm.
10. Blade of Grass
There are over 10,000 grass species, and most of them are usually within a single continent. Some can be thicker, taller, shorter, or even wider than others.
Therefore, it is hard to generalize the size of grasses worldwide. Most would therefore be around 1-4 mm thick.
11. Plate Glass
Plate glass, also known as sheet glass, is a type of glass usually sold as pane. These are used for glass doors, windows, windscreens, and transparent walls.
These glasses can be bent to achieve specific shapes and designs. Plate glass panes come in different shapes and sizes, with the thinnest being around 1 millimeter.
12. SIM Card
A SIM card is an integrated circuit (IC) for securely storing international mobile subscriber identity numbers. Subscribers can use their mobile phones to receive calls, send messages or connect to internet services.
SIM cards must follow global size standards, around 1 millimeter thick. They can fit almost all phones in the world.
13. Memory Card
A memory card is an electronic data storage device for storing digital information using flash memory. These work for digital portable electronic devices.
To add memory to these devices, you need a card in a socket instead of a protruding flash disk. Memory cards are almost the same size as SIM cards and are roughly 1 mm thick.
14. Copper Wire
Copper wire is used in many applications like power generation, transmission, distribution, telecommunications, and electronic circuitry.
Copper and copper alloys are great for making electrical contacts for their excellent electrical conduction. In addition, copper wires for electrical uses tend to be thinner at only 1 mm.
15. Scalpel
A scalpel, bistoury, or lancet is a small yet sharp blade instrument for performing surgeries, podiatry, anatomical dissection, and various crafts.
Scalpels can be single-use or reusable. These blades vary in thickness for precise dissections. A scalpel is about 1 millimeter thick, some even thinner at 0.3 mm.
16. Derma Roller Needle
Derma rollers are used widely in makeup activities like promoting hair growth and improving the skin surface. These rollers have needles that poke the skin to trigger pigmentation.
These needles are small, only 1 mm thick and surround the entire roller. If you are wondering, these needles do not hurt, and if you find one painful to use, it could be damaged or fake.
It is true when they say learning never stops. Every day, you learn something new, whether on the internet, in your office, at home, or anywhere. If you have gone through this list, at least you know something you did not before. There are other minor details about these items that you may have never known. Keep reading to expand your knowledge about things surrounding you.
The dimension of stuff has been an interest of mine ever since I was a child. What I believe is most fascinating about the dimension of stuff is how extremely long, tall and wide some objects are both on earth and in the universe.
