Quantity is the weight of paper per unit area, expressed in grams per square meter. It is the basic basis for measuring paper. The minimum amount of paper was 25 g / m2, with a maximum of 250 g / m2. The quantity can be divided into dry quantitative and air dried ration. The former refers to the amount of water that is completely dry and water equals zero. The latter refers to the amount of water that is released at a certain moisture level. Usually the term "quantification" refers to the latter. Quantitative determination should be carried out under standard temperature and humidity conditions (temperature 23, 1 degrees above, relative humidity 50 and 2%).
500 identical sheets of paper are called a ream, and the weight of a ream is called the weight of that kind of paper. There are also 480 or 1000 orders in the world.
