The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

Paper weight is sometimes stated using the "#" symbol. For example, "20#" means "20 pounds per basis ream of that kind of paper". When the density of a ream of paper is given in pounds, it is often accompanied by its "M weight" (M is 1000 in Roman numerals). The M weight is the weight (in pounds) of 1000 cut sheets.
Weighing scale to determine paper weight. Paper density is a paper product's mass per unit volume.The density can be calculated by dividing the grammage of paper (in grams per square metre or "gsm") by its caliper (usually in micrometres, occasionally in mils).
A special type of area density is called column density (also columnar mass density or simply column density), denoted ρ A or σ.It is the mass of substance per unit area integrated along a path; [1] It is obtained integrating volumetric density over a column: [2] =.
The S.I. unit for the mold constant B is seconds per metre squared (s/m 2). [4] According to Askeland, the constant n is usually 2, however Degarmo claims it is between 1.5 and 2.
a wet process similar to pulp mills in which the fibers are softened and under heat and pressure the ligin in the fibres is used to create boards. The boards are limited to approximately 25 mm thickness; thicker boards are made by gluing (with modified starch or PVA wood glue). Additives such as latex or bitumen are added to increase water ...
