Basically they don't. The gsm are grams per square meter and therefore give you the density of the paper. The lbs are the pounds per ream. A ream is (most often but not always) 500 standard-sized sheets, and different types of paper have different standard sheet sizes. So this measurement unit is nuts, because it tells you exactly nothing about the paper. No idea why it is still used, must have something to do with wrong ideology. On this page you can find a converter that takes the size of the paper into account to convert to gsm: http://www.stillcreekpress.com/paper-weight-conversion-tool/ Nice Greetings Anna from Vienna, Austria
