1. What is Paper Weight Calculation?

The paper weight calculation determines the total weight of a paper product based on its area and grammage (GSM). This is essential for shipping, packaging, and cost estimation in the paper industry.

2. How Does the Calculator Work?

The calculator uses the paper weight formula:

Where:

• \( Area \) — Area in square meters (m²)
• \( GSM \) — Grams per square meter (g/m²)
• \( Weight \) — Result in kilograms (kg)

Explanation: The formula converts the area and density (GSM) into total weight, with division by 1000 to convert grams to kilograms.

3. Importance of Paper Weight Calculation

Details: Accurate paper weight calculation is crucial for determining shipping costs, packaging requirements, and material specifications in printing and paper manufacturing.

4. Using the Calculator

Tips: Enter area in square meters and GSM (grams per square meter). Both values must be positive numbers. The result will be displayed in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: What is GSM in paper?
A: GSM stands for grams per square meter, a measure of paper density or thickness. Higher GSM indicates thicker, heavier paper.

Q2: How do I measure paper area?
A: For rectangular sheets, multiply length by width in meters. For rolls, multiply length by width of the roll.

Q3: What are typical GSM values for different paper types?
A: Copy paper: 70-100 GSM, business cards: 250-400 GSM, magazine covers: 150-300 GSM.

Q4: Why divide by 1000 in the formula?
A: This converts the result from grams to kilograms (1 kg = 1000 g) for more practical weight measurements.

Q5: Can this calculator be used for cardboard?
A: Yes, the same formula applies to any sheet material where GSM is known, including cardboard and other paper products.
