The higher the number code printed on the back of all sandpaper the finer the grit. With a little practice you can begin to understand what grit is appropriate for any given job. For instance, I refinish hardwood floors and it requires three courses of sanding. To help quickly remove an old finish from hardwood floors I start with a very course #20 sandpaper. It is so rough that it removes a large amount of material pretty quickly. Then, when I have sanded the floor down to bare wood I "step up" to 60 grit sandpaper. Once I've gone over the entire floor with the 60 grit I "step up" again to the finer 100 grit paper. When refinishing wood floors or furniture it is necessary to use several courses of sanding to help remove the deep scratches created by the rougher grits of sandpaper. I hope this helps.

The 300 grit sandpaper is finer than the 180 grit. Grit numbers indicate the size of the abrasive particles; a higher number means smaller particles and a smoother finish. Therefore, 300 grit will produce a smoother surface compared to 180 grit, which is more coarse.
If you are priming bodywork, filler; be sure to finish all filler in 180 grit sandpaper, then feather edge paint starting with 180 grit, finishing with 320 grit. Thoroughly clean surface and mask accordingly. Apply corrosion protection and then prime. If you are going to prime a complet vehicle, be sure all nicks and scratches are feather edged with above method. The rest of the vehicle can then be sanded with 320 grit and primed with above method.
Sandpaper currently is available in six different grit sizes. Every grit size is used for a different project. The sizes are 40-60, 80-120, 150-180, 220-240,280-320, and 360-600.
terms used mostly on sand paper, emery cloth, or other fine abrasive materialYou should always know the type of wood you are finishing before starting any sanding. The type of wood you are sanding has a direct relationship to the grit used for final sanding. There are two basic types of wood - softwoods and hardwoods.Typical softwoods are Pine and Fir. Softwoods can be finish sanded with 150 or 180 grit prior to the application of primer. Please see Grit Guide for more information:Grit GuideVery Fine (220) For light sanding between stain and sealer. Fine (150-180) For final sanding or cleaning of wood surfaces. Medium (100-120) For moderate removal of surface imperfections. Course (60-80) For heavy removal of wood and coatings. * http://www.nortonconsumer.com/Data/Element/Node/Application/Application_edit.asp?ele_ch_id=A0000000000000001555"What are the grit sizes equivalent to?"

You have to start out with a rough grit and work your way down to a fine grade.If it's necessary you start with an 80 grit sandpaper.Then you go over it again with a 120 or 180.If you want it even smoother you go to a 220.You'll need more of the finer grits as they're more easily worn down.
Yes, you can polish an SCH stainless steel pipe (40 1 1/2") with a 180 grit.
You will get a better result using drywall mesh cloth, 2 grades about 120 and 180.
A reflex angle is between 180˚ and 360˚. (An obtuse angle is between 90˚ and 180˚.)
It is a reflex angle that is between 180 and 360 degrees.
prime numbers between 170 and 180 = 173, 179
There are all the angles between 180 and 270that lie between 180 degrees and 270 degrees angles
22 158 + 22 = 180 180 - 22 = 158 180 - 158 = 22
