Weight
The Weight attribute indicates the weight of the media used, measured in grams per square meter (gsm) or pounds (lbs).
The basis weights of most North American stock types are measured in pounds (lbs). To convert to gsm, multiply the basis weight by the appropriate conversion factor.
For example, the metric weight of a 50lb bond stock is calculated as follows:
Basis Weight x Conversion Factor = 50 x 3.76 = 188gsm.
The appropriate conversion factor for stock types is listed in the following table:
