1. What is GSM?

GSM stands for Grams per Square Meter, which is a metric measurement of the weight and density of fabric. It indicates how many grams a square meter of fabric weighs and is commonly used in the textile industry to specify fabric quality and thickness.

2. How Does the Calculator Work?

The calculator uses the GSM formula:

Where:

• \( Weight \) — Sample weight in grams (g)
• \( Area \) — Sample area in square meters (m²)

Explanation: The formula calculates the fabric density by dividing the weight of a fabric sample by its area, providing the GSM value that represents the fabric's weight per unit area.

3. Importance of GSM Calculation

Details: GSM is crucial for determining fabric quality, durability, and appropriate usage. Higher GSM indicates heavier, denser fabric suitable for winter clothing or heavy-duty applications, while lower GSM indicates lighter fabric for summer wear or delicate applications.

4. Using the Calculator

Tips: Enter the weight of your fabric sample in grams and the area in square meters. Ensure accurate measurements for precise GSM calculation. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical GSM range for different fabrics?
A: T-shirts: 150-200 GSM, Denim: 300-400 GSM, Towels: 400-600 GSM, Canvas: 500-1000 GSM.

Q2: How do I convert GSM to ounces per square yard?
A: Multiply GSM by 0.0295 to get ounces per square yard (oz/yd²).

Q3: Why is GSM important in fabric selection?
A: GSM helps determine fabric thickness, durability, warmth, and appropriate usage for different applications and seasons.

Q4: How do I measure fabric area accurately?
A: Use a fabric cutting die or precise measuring tools to cut a known area (e.g., 0.01 m² or 0.1 m²) for consistent results.

Q5: Does GSM affect fabric price?
A: Generally, higher GSM fabrics are more expensive due to increased material usage, but other factors like fiber quality and construction also affect price.
