mass per unit area Explanation: 'In the United States the customary or commercial term for expressing the “weight” per unit area (more properly “mass per unit area”) of paper has been “basis weight,” “ream weight,” or “substance.” These are defined as the mass in pounds of a ream of a given sheet size and number of sheets (usually 500 sheets, occasionally 480 sheets). In most other countries the mass per unit area is expressed in grams per square meter, g/m2.' -------------------------------------------------- Note added at 9 mins (2014-03-10 16:09:49 GMT) -------------------------------------------------- 'Paper density (also known as basis weight and *grammage*) is a term used in the pulp and paper industry and also for fabric industry to denote a measure of mass of the product per unit of area for a type of fabric, paper or paperboard. The term "density" is not used in its traditional sense of mass per unit volume.' http://en.wikipedia.org/wiki/Paper_density Reference: http://www.tappi.org/content/tag/sarg/t410.pdf |
