Paper weight US/UK conversion

In the US they sell paper in pounds (lbs), then they have different categories, Bond, Text, Book, Cover, Index and Tag and to really confuse it they show the weight as a measurement of 500 sheets in its untrimmed size. An uncut sheet of Bond paper is 17 x 22 inches, and an uncut sheet of Cover paper is 20 x 26 inches. So 500 sheets of Bond paper (17” x 22”) weighs 20 lbs, even when cut to Letter size (279 x 215mm) it will be labelled as 20 lb. 500 sheets of Cover paper (20 x 26 inches) weighs 65 lbs, trimmed to tabloid size (432 by 279mm) would still be marked as 65lb.

Bond 17″ x 22″
Book, Text 25″ x 38″
Bristol 22 1/2″ x 28 1/2″
Cover 20″ x 26″
Index 25 1/2″ x 30 1/2″
