Thin
A typical sheet of paper is about 0.1 millimeters thick.
To find the thickness of one sheet of paper, divide the total thickness of the pack (50mm) by the number of sheets in the pack (500 sheets). Each sheet of paper would be 0.1mm thick.

The thickness of 30,000 pieces of paper depends on the thickness of a single sheet. A standard sheet of office paper is typically about 0.004 inches thick. To calculate the total thickness: 30,000 \times 0.004 \text{ inches} = 120 \text{ inches} So, 30,000 pieces of standard office paper would be approximately 120 inches thick.
Folding the piece of paper does not change the thickness of the piece of paper. However, the thickness of the folded paper would be twice that of the original sheet of paper.
Depends on what paper you're talking about. The average sheet of 20lb copier paper is 0.0038 inches thick; whereas the average sheet of cardstock is 0.0175 inches thick. For a great resource of various thicknesses visit http://iconix.biz/info/paper-weights.htm
20 lb. bond paper isn't 20 pounds of bond paper, but rather the basis weight, which measures the density of the paper based on how heavy 500 sheets of that paper is. A single sheet of this type of paper is, on average, 4/1000 of an inch thick.
If you could hypothetically fold a standard sheet of paper 100 times, it would be about 1x10^30 meters thick, which is significantly thicker than the observable universe. This calculation involves exponential growth and is practically impossible to achieve due to physical limitations.
Assuming a standard sheet of paper is 0.1mm thick, the height of a million sheets of paper stacked on top of each other would be 100 meters (328 feet).

Paper measurement If we're talking about weight, the worldwide standard is gsm (grams per square meter), and there are no practical differences in the measuring technique; nevertheless, we may measure paper thickness by GSM. A4 paper measures 210 mm by 297 mm.
