Formula for “Length to Kg”
To convert fabric length (in meters or yards) to kilograms (kg), you need the following formula:
Formula (for meters):
Weight (kg) = (Length × Width × GSM) / 1000000
Where:
- Length = fabric length in meters
- Width = fabric width in centimeters
- GSM = fabric weight in grams per square meter
- 1000000 = conversion factor to get weight in kg (since width is in cm and GSM is in g/m²)
Table of Contents
Converting fabric length to kg is important in textile production. It helps mills and buyers know the weight of fabric in bulk. This is useful for both pricing and inventory. As a textile engineer, I have used this formula in factories, sampling units, and production lines.

What is Length to Kg Conversion?
Length to kg means finding fabric weight from its length. You need three main values: fabric length in meters, fabric width in centimeters, and GSM (grams per square meter). This conversion helps during fabric costing, bulk production, and weight estimation.
Formula for Length to Kg
You can calculate fabric weight in kg using this simple formula:
Weight (kg) = (Length × Width × GSM) / 1,000,000
- Length is in meters
- Width is in centimeters
- GSM is grams per square meter
- The division by 1,000,000 converts the value to kilograms
Example Calculation
If you have a fabric of
Length = 100 meters
Width = 100 cm
GSM = 160
Then,
Weight = (100 × 100 × 160) / 1,000,000
= 1.6 kg
This means your 100-meter roll weighs 1.6 kilograms.
Why Is This Conversion Important?
In textile production, every fabric order needs weight estimation. Factory managers use this formula before knitting, weaving, or dyeing. Brands use this to set shipping weight and cost.
Helps in Fabric Costing
Fabric suppliers calculate the cost per kg. So, they must know how many kg are in one roll. If the length is known, weight must be calculated. This formula makes that easy.
Useful in Export and Import
In international trade, fabric is usually billed by weight. If a buyer orders 100 kg of fabric, mills must convert length into kg using this formula to match that order.
Supports Inventory Control
Textile warehouses track fabric by both length and weight. This calculator helps inventory managers convert between the two as needed.
Units Required for Calculation
To use the length to kg calculator correctly, ensure your values are in:
- Meters for fabric length
- Centimeters for fabric width
- GSM for fabric weight
If your fabric length is in yards, convert it to meters first. 1 yard = 0.9144 meters.
Practical Use in Factory
In my experience, this formula helps during:
- Knitting fabric production
- Roll weight estimation before dyeing
- Export weight checking for shipping
- Sampling during product development
Operators, supervisors, and quality controllers use this method daily. Many factories have built-in calculators based on this.
GSM Importance in Conversion
GSM (grams per square meter) indicates the weight of a fabric. A higher GSM means a heavier fabric. To convert fabric length to weight, GSM plays a big role.
Common GSMs:
- T-shirts: 160-180 GSM
- Hoodies: 280-320 GSM
- Towels: 400-600 GSM
Knowing the correct GSM ensures accurate conversion.
Why Use a Calculator?
Manual calculation takes time. A fabric calculator gives instant results. It avoids mistakes. Anyone can use it—whether a buyer, merchandiser, or textile student.
