Speaker 1: Welcome to Brainstuff from house stuff works dot com, where
Speaker 1: smart happens Him Marshall Brain with today's question, how much
Speaker 1: does twenty pound bond paper way? When you go to
Speaker 1: the store and buy a printer paper, it's normally described
Speaker 1: as twenty pound bond paper, But what does that actually mean?
Speaker 1: The way we talk about paper in the United States
Speaker 1: is amazingly convoluted. The short answer is that five hundred
Speaker 1: sheets of bond paper with the size of seventeen inches
Speaker 1: by twenty two inches have a weight of twenty pounds.
Speaker 1: The manufacturer would cut a sheet that big into four
Speaker 1: letter sized sheets, so a five hundred sheet ream of
Speaker 1: twenty pound bond paper actually weighs five pounds. Each sheet
Speaker 1: of paper therefore weighs one one of a pound, or
Speaker 1: about four and a half grams. If it was something
Speaker 1: other than bond paper, then the size of the standard
Speaker 1: sheet used to determine the weight might be different. For example,
Speaker 1: bristol paper is heavier and stiffer, kind of like the
Speaker 1: paper and a Manila file folder. It's standard sheet size
Speaker 1: is twenty two and a half inches by twenty eight
Speaker 1: and a half inches. In general, the more a sheet
Speaker 1: of a certain grade of paper ways the thicker it is.
Speaker 1: You can purchase twenty pound or twenty four pound bond
Speaker 1: paper at the office supply store. The twenty four pound
Speaker 1: bond paper is thicker, heavier, and more opaque than twenty
Speaker 1: pound bond. The metrics system has a much better way
Speaker 1: of measuring paper. A zero paper is a square meter
Speaker 1: of paper. One side is eighty four point one centimeters long,
Speaker 1: and the other is a hundred eighteen point nine centimeters.
Speaker 1: The longer sides length is the square root of two
Speaker 1: longer than the short sides length. A one paper is
Speaker 1: half of an A zero sheet, preserving the square root
Speaker 1: of two rule. A two paper is half of an
Speaker 1: a one sheet, and so on, and paperweight is measured
Speaker 1: in grams per square meters, so it's very easy to
Speaker 1: figure things out. For more on this and thousands of
Speaker 1: other topics, is it how stuff Works dot com
