the smoothness of the surface basically. i.e. 1000 grit sandpaper would have 1000 particles of grit per cm or inch. 200 grit would be much rougher as the particals are bigger, as there are only 200 per unit of measurment. hope this helps

Why work to a recognised standard when producing engineering drawings?
The simplest answer is that working to a standard means that anyone can read the drawing. If there is no standard the symbols used on the drawing (weld type and size, surface finish, even the dimensioning of the components) would vary from one drawing (or draughtsperson) to another and cause confusion. Engineering drawings use a large number of symbols to denote operations and instructions (which reduces the time taken to draw them and the size of "paper" they're drawn on). Imagine the potential problems if one person used a symbol to mean "weld" and another one used the same (or similar) symbol to mean "do not weld".

What does for reference only mean on an engineering drawing?
It means you can't look at it or you'll go catatonic Cute. Actually, it means that the entity that is being "referenced", usually a dimension, should NOT be inspected. It might be an overall length of the part. This might be a "cut length" for the machinist where the actual required dimension is shown elsewhere on the drawing.
What does micro-inch finish mean and how is it measured?
micro means 10 to the -6 inches so for example 32 microinches would be 0.000032 inch. With respect to surface finish it is basically a measure of the height of the "peaks and valleys" of the finish of a surface. There are different ways to measure this (RMS, etc.) but that is basically what it means. So for example a 125 microinch finish is a typical machined fnish for metals but a 32 is much better and would be called out where sealing surfaces may be needed.
