1. What is GSM and OZ/yd²?

GSM (grams per square meter) and OZ/yd² (ounces per square yard) are two common units used to measure fabric weight in the textile industry. GSM is the metric standard, while OZ/yd² is commonly used in countries following imperial measurements.

2. How Does the Conversion Work?

The calculator uses the standard conversion formula:

Where:

• \( GSM \) — Grams per square meter (g/m²)
• \( oz/yd² \) — Ounces per square yard
• \( 33.905 \) — Conversion factor derived from unit relationships

Explanation: This conversion factor accounts for the relationship between ounces and grams (1 oz = 28.3495 g) and between square yards and square meters (1 yd² = 0.836127 m²).

3. Importance of Fabric Weight Conversion

Details: Accurate fabric weight conversion is essential for international trade, quality control, product specifications, and ensuring consistency in manufacturing processes across different measurement systems.

4. Using the Calculator

Tips: Enter the fabric weight in ounces per square yard (oz/yd²). The value must be greater than 0. The calculator will automatically convert to grams per square meter (GSM).

5. Frequently Asked Questions (FAQ)

Q1: Why is 33.905 the conversion factor?
A: The factor is derived from: 1 oz/yd² = (28.3495 g/oz) ÷ (0.836127 m²/yd²) = 33.905 g/m²

Q2: What are typical fabric weights?
A: Light fabrics: 100-200 GSM (3-6 oz/yd²), Medium: 200-300 GSM (6-9 oz/yd²), Heavy: 300+ GSM (9+ oz/yd²)

Q3: Which industries use this conversion?
A: Textile manufacturing, fashion design, upholstery, technical textiles, and quality control laboratories.

Q4: Is the conversion exact?
A: The conversion factor 33.905 is standard, but slight variations may exist due to rounding in different industry standards.

Q5: Can I convert GSM to oz/yd²?
A: Yes, use the reverse formula: oz/yd² = GSM ÷ 33.905
