1 million is 100^3 (i.e. a cube 1 metre across, contains a million 1 cm cubes) 1 billion is 1000^3 (1 m cube contains a billion 1 mm cubes) 1 trillion is 10,0

1 million is 100^3 (i.e. a cube 1 metre across, contains a million 1 cm cubes)
1 billion is 1000^3 (1 m cube contains a billion 1 mm cubes)
1 trillion is 10,000^3 (I can't visualize 0.1 mm, so increase size: the big cube is now 10 m on side, with 1 mm parts)
So the million and billion you could have on your desk made of parts that you can see and handle; the trillion is just a bit too big for that, you'd need a big room with a high ceiling.
Edit: and, of course, you can also see a million in 2D. A sheet of grid paper 1 m across, with 1mm grid squares. Or, more practically, try counting the pixels on a 720p monitor: 921600 pixels on that screen. Use checkerboard pattern.

- gilleain 3y agoThere absolutely are when it comes to materials like pens, but I bought a set of 3 pens (0.1 mm, 0.3 mm, 0.5 mm) for less than ten GBP. Specifically, Mitsubishi pencil co. unipen fine line. Sure you can probably buy much more expensive examples, but it's not essential. (Side note : don't try to use a gel ink pen across varnish, or it stops working until you clean it off with solvent)
- hnuser123456 3y ago0.1mm is about the thickness of a sheet of paper.
- HPsquared 3y agoA 0.1mm cube is like a grain of fine sand, can't really see the size of it. I couldn't imagine stacking them by hand with tweezers, but just about doable for 1mm.
- HPsquared 3y agoThinking again about it, you could have sheets of paper stacked into a cube. 1 m^2 sheets, with 0.1mm checkerboard pattern, stacked a metre high. That's some fine detail...
