Paper weight conversions
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

You have to know the real units. In the UK (and almost the whole world) paper is weighed in grams per square meter for any type of paper.
In the US, the weight in pounds is given for 500 sheets of basis sheet. Basis sheet is NOT the final piece you hold in your hands, but the larger sheet it is cut from. There are different size basis sheets for bond, index stock, book paper etc.
For bond (common office copy paper, stationery), the basis size is 17" x 22" (or 4 sheets of US letter). After much math, left as exercise for reader, for BOND paper, the conversion is 3.76. US 20 lb paper is 75.2 gsm. This constant has other (significantly different) values for other types of paper because the basis sheet for weight is a different size. VERY confusing.
