The paper industry offers abundant resources, but sometimes
the wealth of paper stocks and weights can be daunting. For
example, paper composition and sheet size can cause some cover
stocks to have very different weights in grams per square
meter (g/sm²). To avoid confusion when using varying weight
paper stocks, consult this chart of equivalent weights.
