1. What is GSM?

GSM stands for Grams per Square Meter, a metric measurement of paper weight or fabric density. It represents the weight of one square meter of the material in grams.

2. How Does the Calculator Work?

The calculator uses the GSM formula:

Where:

• \( Thickness \) — Material thickness in millimeters (mm)
• \( Density \) — Material density in grams per cubic centimeter (g/cm³)
• \( 1000 \) — Conversion factor (mm to m and cm³ to m³)

Explanation: The equation converts thickness and density into weight per unit area by accounting for the necessary unit conversions.

3. Importance of GSM Calculation

Details: GSM is crucial in industries like paper manufacturing, textiles, and packaging to ensure consistent quality and meet product specifications.

4. Using the Calculator

Tips: Enter thickness in millimeters and density in g/cm³. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between GSM and thickness?
A: Thickness measures how thick a material is, while GSM measures its weight per unit area, which depends on both thickness and density.

Q2: What are typical GSM values for paper?
A: Standard copy paper is about 80 GSM, cardstock ranges from 200-300 GSM, and business cards are typically 300-400 GSM.

Q3: How do I measure density if I don't know it?
A: Density can be calculated by dividing the weight of a material sample by its volume (mass/volume).

Q4: Can this calculator be used for all materials?
A: Yes, as long as you know the material's thickness and density, this calculation works for paper, fabric, plastic, metal, etc.

Q5: Why multiply by 1000 in the formula?
A: This converts mm to meters (×1000) and cm³ to m³ (×1000000), with net conversion factor of 1000 (1000000/1000).
