Why You Need Kg to Meter Conversion in Yarn Calculation
Textile engineers work with yarn every day. Yarn is often purchased or sold by the kilogram. However, most machines and processes require measurements in meters. To match machine capacity or plan dyeing batches, we must convert yarn weight in kilograms to yarn length in meters. This conversion helps maintain production efficiency in spinning, weaving, knitting, and dyeing.

Formula to Convert Kg to Meters of Yarn
The formula to convert kg to meters of yarn is:
Meters = (Kilograms × 1000) / Tex
What is Tex in Yarn?
Tex is a unit of yarn thickness or linear density. It shows how heavy the yarn is per unit length.
1 Tex = 1 gram per 1000 meters of yarn.
If the tex is higher, the yarn is thicker. If tex is lower, the yarn is finer. We need tex to calculate the length of yarn from a given weight.
Why Multiply by 1000?
We multiply the weight in kilograms by 1000 to convert it into grams. The tex unit works with grams, so this step is needed for the correct result.
Example of Kg to Meter Yarn Conversion
Let’s take a simple example:
- Yarn Weight = 2 kg
- Yarn Tex = 20
Now use the formula:
Meters = (2 × 1000) ÷ 20 = 2000 ÷ 20 = 100 meters
So, 2 kg of 20 tex yarn gives 100 meters of yarn.
If the tex is finer, the same 2 kg will give more length. If the tex is thicker, the same 2 kg will give less length.
Why This Conversion is Useful in Textile Manufacturing
This conversion is important in many parts of textile production. From spinning to knitting and from weaving to winding, accurate yarn length matters. Below are some key areas where this formula helps.
Spinning Mill Operations
Spinners produce yarn in kilograms. But cones are measured by length. Operators must convert kg to meters to control production and packaging.
Dyeing Batch Calculation
In yarn dyeing, dye quantity depends on the length of the yarn. If the weight is known, the length must be calculated using the tex value.
Knitting and Weaving Setup
Machines in knitting and weaving need yarn in meters. Kg-based storage needs to be converted into meters before machine loading.
Yarn Trading and Export
Buyers often request yarn in meters. Suppliers use the formula to give an accurate length for every yarn type.
Benefits of Using the Kg to Meter Formula
Using this formula has many benefits in real production:
- Reduces material loss
- Helps with accurate machine setup
- Ensures correct dye usage
- Prevents order mismatch
- Helps in planning and reporting
- Improves yarn stock tracking
Default Values You Can Use for Quick Test
You can test this formula with common yarn values. For example:
- Yarn Tex: 30 (medium cotton yarn)
- Weight: 1 kg
Meters = (1 × 1000) ÷ 30 = 33.33 meters
If you increase the weight to 5 kg with the same tex:
Meters = (5 × 1000) ÷ 30 = 166.67 meters
This shows how weight and tex directly affect total yarn length.
Tips from a Textile Engineer
As a textile engineer, I use this formula often. In my work with knitwear factories, I calculate yarn needs per style. If a style needs 800 meters of 24 tex yarn, I reverse the formula to find kg:
Kilograms = (Meters × Tex) ÷ 1000
Kilograms = (800 × 24) ÷ 1000 = 19.2 kg
This helps us order the right quantity from suppliers. We avoid excess stock and reduce waste. Every knitting floor, dyeing section, and yarn buyer uses this calculation daily.
