Enter the total number of pounds of paper and select the type of paper into the calculator to determine the grams per square meter.

Paper Weight Conversion Formula

The following formulas are used to convert the weight of paper in pounds to grams per square meter.

For Text:

Grams Per Square Meter = X * 1.481

For Cover Paper:

Grams Per Square Meter = X * 2.707
  • Where X is the total paper weight in pounds.

Paper Weight Conversion

What is the conversion of paperweight?

A paperweight conversion is a term often used to describe the conversion of the weight of paper in pounds to grams per square meter of paper.

This is not a strict weight-to-weight conversion. Instead, this is a weight-to-weight per area conversion. The formulas used above for this conversion assume standard paper sizes.

Example Problem

How to perform a paper weight conversion?

First, determine the total amount of weight of paper in pounds.

For this example, there is a total of 40 lbs of paper.

Next, determine the type of paper.

In this case, the paper is simple text paper.

Finally, calculate the GSM using the formula above:

Grams Per Square Meter = X * 1.481

Grams Per Square Meter = 40 * 1.481

Grams Per Square Meter = 59.24

FAQ

What is GSM in paper terms?

GSM stands for Grams per Square Meter and is a standard unit of measurement for the weight of paper. It indicates the quality and thickness of paper; the higher the GSM, the heavier and generally thicker the paper.

Why is paper weight conversion important?

Paper weight conversion is crucial for various industries, especially in printing and packaging, as it helps in determining the right type of paper for specific needs. It ensures compatibility with printing machines, affects postage costs, and influences the perception of quality in printed materials.

Can the same weight conversion formula be used for all types of paper?

No, different types of paper have different conversion formulas due to variations in density and composition. For example, text paper and cover paper use different conversion factors as illustrated in the provided formulas.

How does the weight of paper affect printing costs?

The weight of paper can significantly affect printing costs. Heavier paper (higher GSM) generally costs more to produce and can also increase postage costs for mailed items. However, it may be preferred for high-end prints due to its quality and durability.
