1. What is Paper Weight Calculation?

The paper weight calculation determines the weight of paper based on its grammage (weight per unit area) and the total area. This is essential in printing, packaging, and paper manufacturing industries.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Grammage \) — Paper weight per square meter (g/m² or GSM)
• \( Area \) — Total area of the paper (m²)

Explanation: The calculation multiplies the paper's density (grammage) by its total area to determine the overall weight.

3. Importance of Paper Weight Calculation

Details: Accurate paper weight calculation is crucial for shipping costs, postage determination, printing press settings, and packaging requirements.

4. Using the Calculator

Tips: Enter grammage in g/m² (GSM) and area in square meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is typical grammage for common paper types?
A: Copy paper is typically 80 g/m², cardstock 200-300 g/m², and newsprint about 45 g/m².

Q2: How do I convert paper weight to pounds?
A: First calculate weight in grams, then divide by 453.592 to convert to pounds.

Q3: Does this work for irregular shapes?
A: Yes, as long as you know the total area in square meters, the shape doesn't matter.

Q4: What's the difference between grammage and basis weight?
A: Grammage is weight per square meter, while basis weight is weight per ream of specific size sheets.

Q5: Can I calculate area if I know weight and grammage?
A: Yes, by rearranging the formula: Area = Weight / Grammage.
