Understanding Paper Basis Weight

Paper basis weight is a measure of the weight of 500 sheets of paper cut to a standard size for that type of paper. It is often expressed in pounds (lb) or grams per square meter (gsm). Understanding paper basis weight is important for determining the thickness and quality of a paper. Different types of paper, such as bond, cover, and text, have different standard sizes and basis weights.

Converting Paper Basis Weight

Converting paper basis weight from pounds to grams per square meter or vice versa can be useful when comparing different types of paper or when working with suppliers who use different measurement systems. To convert from pounds to grams per square meter, you can use the formula gsm = lb * 453.59237 / (width * length). To convert from grams per square meter to pounds, you can use the formula lb = gsm * (width * length) / 453.59237. It’s important to note that these formulas are based on the standard size of the paper being used.

Using a Paper Basis Weight Conversion Chart

Using a paper basis weight conversion chart can simplify the process of converting between pounds and grams per square meter. These charts typically list common basis weights for different types of paper and provide the equivalent weight in the other measurement system. By referencing a conversion chart, you can quickly and easily determine the equivalent basis weight for the type of paper you are working with.
