1. What is GSM?

GSM (grams per square meter) is a metric measurement of the weight of paper, fabric, or other sheet materials. It indicates how many grams a single square meter of the material weighs.

2. How Does the Calculator Work?

The calculator uses the GSM formula:

Where:

• \( Mass \) — Weight of the material in grams
• \( Area \) — Area of the material in square meters

Explanation: The formula calculates the density of the material by dividing its weight by its area.

3. Importance of GSM Calculation

Details: GSM is crucial in industries like paper manufacturing, textiles, and packaging as it determines the quality, thickness, and durability of materials.

4. Using the Calculator

Tips: Enter the mass in grams and area in square meters. Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical GSM range for paper?
A: Standard copy paper is typically 80 gsm, while cardstock ranges from 120-300 gsm.

Q2: How does GSM relate to fabric weight?
A: Higher GSM indicates heavier fabric. T-shirts are typically 150-200 gsm, while winter fabrics may be 300+ gsm.

Q3: Why is GSM important in South Africa?
A: South Africa's textile and paper industries use GSM as a standard measurement for quality control and product specifications.

Q4: Can I calculate GSM with imperial measurements?
A: Yes, but you must first convert ounces to grams and square feet/yards to square meters for accurate results.

Q5: How precise should my measurements be?
A: For accurate GSM calculation, measure mass to at least 0.1g precision and area to 0.0001 m² precision.
