How big is the average grain of sand?
The technical definition of sand is classic grains between 0.0625mm (62.5 μm) and 2mm. Let us take 1mm as an average. Let's also assume 100% sorting, i.e. the sand has been sieved so all particles are 1mm. A billion is 10^9 or 1,000,000,000. The cube root is 1,000 so a billion is 1,000x1,000x1,000.

The grain of a wood is the direction in which most or all of the wood fibers are pointing, and one of the axioms of woodworking is to sand with the grain.

How to identify the direction of wood grain?
1. Identify the direction of the wood grain by examining the wood and looking for the lines. Usually these are obvious at a glance, but sometimes close examination might be necessary. Ignore disruptions in the grain, such as knots.
What tools do you use to sand wood?

In a technical sense, sanders using a rotating pad -- like rotary tools and orbital sanders -- sand neither with nor against the grain, but they still leave behind very minor scratches, or "squigglies." If you have no intention of finishing the wood object in question, these scratches are irrelevant; but if you do, a final sanding with the grain is essential.
What happens if you sand wood with a larger grit?
The larger the grit (60 vs. 100) will leave larger 'gouges' in the wood when sanding. The grit is an 'average' size of the grains and the larger ones can leave deeper marks. Sanding with the grain the marks are much less likely to cut across the wood grain, leaving an obvious trail.

In fact, one common suggestion for users of random-orbital sanders is to do a final light pass by hand with the grain to clean up any remaining cross-grain scratches.
Can you sand along the grain?
So by sanding along the grain you will need less time with finer and finer sandpaper to get the same finish. While you can do the same thing by sanding across the grain it will take much longer.
Do random orbit sanders cut cross grain?
Random orbit sanders do a decent job of minimizing the worst of the cross-grain cutting. I've also found that the orbit sanding disks have a smaller variance in their grit.
Does sanding across grain cut faster?
