GSM Formula:
| From: | To: |
GSM (Grams per Square Meter) is a standard measurement for fabric weight that indicates the mass per unit area of fabric. It's an important quality parameter in the textile industry.
The calculator uses the GSM formula:
Where:
Explanation: The formula converts the weight per unit area from g/cm² to the standard g/m² unit by multiplying by 10,000 (since 1 m² = 10,000 cm²).
Details: GSM measurement is crucial for quality control, pricing determination, and ensuring fabric meets specific requirements for different applications. It helps manufacturers maintain consistency and customers verify product specifications.
Tips: Enter the weight of your fabric sample in grams and the area in square centimeters. Both values must be positive numbers. For accurate results, measure the sample precisely using calibrated instruments.
Q1: What is a typical GSM range for different fabrics?
A: Light fabrics: 30-150 g/m², medium: 150-350 g/m², heavy: 350+ g/m². Specific ranges vary by fabric type and intended use.
Q2: Why is GSM important in textile manufacturing?
A: GSM determines fabric quality, durability, and suitability for different applications. It affects pricing, production planning, and customer satisfaction.
Q3: How should I measure fabric samples for GSM calculation?
A: Use a standardized sample cutter for consistent area measurement and a precision scale for weight measurement. Ensure samples are conditioned in standard atmosphere.
Q4: Can GSM vary within the same fabric roll?
A: Yes, minor variations can occur due to manufacturing inconsistencies. Multiple samples from different locations should be tested for accurate representation.
Q5: How does GSM relate to fabric thickness?
A: While related, GSM measures weight density, not thickness. Two fabrics with the same GSM can have different thicknesses depending on fiber density and construction.
