Weight (lbs) per ream: 0

The GSM to LBS Paper Calculator is a vital tool for converting the weight of paper from grams per square meter (GSM) to pounds per ream. This conversion is essential for understanding paper weight in different units, especially when dealing with international paper standards. The calculator simplifies the conversion process, enabling users to quickly determine the weight of paper in pounds for a standard ream of 500 sheets.

Formula of GSM to LBS Paper Calculator

To effectively use the GSM to LBS Paper Calculator, it is important to understand the formula involved:

To convert GSM (grams per square meter) to pounds per ream (500 sheets), use the following formula:

Weight (lbs) = (GSM * Area of one sheet in square meters * Number of sheets in ream) / 453.59237

Here's the breakdown:

GSM: Weight of the paper in grams per square meter.

Area of one sheet in square meters: For a standard sheet size of 8.5 x 11 inches, convert the dimensions to meters.

8.5 inches = 0.2159 meters 11 inches = 0.2794 meters

Area of one sheet = 0.2159 meters * 0.2794 meters = 0.0603 square meters

Number of sheets in a ream: 500 sheets.

Conversion factor: 1 pound = 453.59237 grams.

Putting it all together in the formula:

Weight (lbs) = (GSM * 0.0603 * 500) / 453.59237


Weight (lbs) = (GSM * 30.15) / 453.59237

Weight (lbs) = GSM * 0.0665
