Documented Textile Industry Formula
Textile Roll Weight & Length Equivalence Formula
- 1. Width in Meters = Width in Inches × 0.0254.
- 2. Grams per Linear Meter (GLM) = GSM × Width in Meters.
- 3. Linear Meters = (KG × 1000) / GLM.
- 4. Linear Yards = Linear Meters × 1.09361.
Worked Calculation Example
Real-World Scenario: A 25 kg roll of 220 GSM single jersey cotton fabric with 60-inch width.
- • Width in meters = 60 × 0.0254 = 1.524 m
- • Weight per linear meter (GLM) = 220 GSM × 1.524 m = 335.28 grams/meter
- • Total Meters = (25 kg × 1000 g) / 335.28 g/m = 74.56 Linear Meters
- • Total Yards = 74.56 m × 1.09361 = 81.54 Linear Yards
A 25 kg roll contains approximately 74.6 meters (81.5 yards) of fabric.
Frequently Asked Questions
How do you convert fabric kg to meters?
Divide the total roll weight in grams (kg × 1000) by the fabric's Grams per Linear Meter (GSM × width in meters). Formula: Meters = (KG × 1000) / (GSM × Width in meters).
What is the difference between GSM and GLM?
GSM (Grams per Square Meter) measures the weight of a 1m × 1m square of fabric. GLM (Grams per Linear Meter) measures the weight of a 1-meter cut across the full roll width. GLM = GSM × Roll Width (in meters).
Why do textile mills sell knit fabric by weight (kg) rather than meters?
Circular knitted fabrics stretch and contract significantly under roll tension, making linear length measurements variable. Weight in kilograms is unaffected by tension or relaxation, providing an exact, verifiable metric for buying and selling.
