I'm confused about the term "pixels per inch"
iPhone 6 has 326 ppi
there's 25.4 millimeter in 1 inch which I can barely see… how much more of 326 pixels inside 1 inch….
So does Pixel have a standard size?
Does 1 pixel have a standard size

You can assign 1 px scrolling to Alt+mousewheel, just open about:config and change the mousewheel.withaltkey.action value to 4. 4 means Scroll the document by a number of pixels. Make sure the mousewheel.withaltkey.sysnumlines is set to false and mousewheel.withaltkey.numlines is 1.
Now you can scroll by one pixel by holding the Alt when using the mousewheel.

The size of a pixel varies by device. For example a 24" monitor running 1024x768 has bigger pixels than a 20" monitor running the same resolution.
The pixel is the smallest dot that can be turned on or off (or given a colour). The higher the resolution (more pixels) for a given display size, the smaller the dots (pixels) and the finer the detail that can be displayed.
