To convert grams per square meter (gsm) to pounds per ream (lb), you can use the conversion factor where 1 gsm is approximately equal to 0.00220462 lb. Thus, 280 gsm is about 0.617 lb per square meter. If you're looking for the weight of a ream (500 sheets) of standard 20x30 inch paper, you would multiply by the area factor, resulting in approximately 140 lb for a ream of 280 gsm paper.
