Calculate the volume of paper from paper thickness and paper weight. The paper volume Vspez is the ratio between these two values, it is not an ordinary volume, but a specific volume. Its unit cm³/g commonly isn't indicated. Normal paper has the volume 1, the higher the value, the thicker is paper of the same weight and the more grippy it is.
The formula is: Vspez = paper thickness * 1000 / paper weight
Example: 80 grams paper with a thickness of 0,1 millimeter has a paper volume of 1.25.
