Talk:Units of paper quantity
Fromthe old "Paper ream" page
In the United States, paper is typically described by a mass in pounds, with 20 pound and 24 pound as common masses. This measurement refers to the weight of 500 sheets of 17 in.×22 in. paper of that type, which the manufacturer could cut into four letter-size reams. Thus, one ream of twenty-pound letter-size paper has a mass of five pounds.
The metric unit for paper thickness, or grammage, is grams per square metre. Since 1 pound is 453.59237 grams, 1 inch is 25.4 mm, and 1 standard ream is 500 sheets of 17 in.×22 in., a paper thickness of 20 pounds per ream corresponds to 75 g/m².
- 1 printer's bale = 5 printer's bundles = 5,070 sheets
Proposed changes to article
What started off as a post-pub quiz argument about the ream turned into an attempt to find some references for this article, which in turn led to an expansion of the whole page. Rather than inflict a load of changes in one bold edit, I have made a draft on my
talk user page. Comments/suggestions are welcome. >MinorProphet (talk) 19:16, 25 September 2011 (UTC)
To be added
The following link has some great information: http://www.papersizes.org/reams-quires.htm I'd like to find reliable sources for the data there, so we could get it into the article. JoeSperrazza (talk) 18:21, 25 December 2014 (UTC)
