1. What is Paper Weight Calculation?

The paper weight calculation determines the total weight of a given quantity of paper based on its dimensions, thickness (GSM), and number of sheets. This is essential for shipping, pricing, and production planning in the paper industry.

2. How Does the Calculator Work?

The calculator uses the paper weight formula:

Where:

• \( Length \) — Length of paper in centimeters
• \( Width \) — Width of paper in centimeters
• \( GSM \) — Grams per square meter (paper thickness)
• \( Sheets \) — Number of sheets

Explanation: The formula first calculates the area weight of one sheet (converting cm² to m² by dividing by 10,000) and then multiplies by the number of sheets.

3. Importance of Paper Weight Calculation

Details: Accurate paper weight calculation is crucial for determining shipping costs, estimating material requirements, calculating postage, and ensuring compliance with packaging specifications.

4. Using the Calculator

Tips: Enter dimensions in centimeters, GSM value (typical values: 80gsm for office paper, 150-300gsm for cardstock), and number of sheets. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does GSM stand for?
A: GSM means "grams per square meter" and indicates the paper's thickness. Higher GSM means thicker, heavier paper.

Q2: How do I convert paper weight to pounds?
A: Multiply the result in kilograms by 2.20462 to get pounds.

Q3: What's the difference between basis weight and GSM?
A: Basis weight measures weight per ream (usually 500 sheets) of a standard size, while GSM measures weight per square meter regardless of sheet size.

Q4: What are common GSM values for different paper types?
A: 35-55gsm for newsprint, 70-100gsm for office paper, 120-150gsm for flyers, 200-300gsm for covers, 300+gsm for cardboard.

Q5: Why divide by 1,000,000 in the formula?
A: This converts cm² to m² (10,000) and grams to kilograms (1,000), combining both conversions (10,000 × 100 = 1,000,000).
