How to convert linear mass density
Linear mass density is mass per unit of length. Textile yarn is rated in tex or denier, while cables, rope and rails are rated in kilograms per meter or pounds per foot.
Every linear mass density unit is a fixed multiple of one base unit, the kg/m. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert den to tex, multiply by 0.1111111111. To go the other way, divide by 0.1111111111.
The converter above does this for you and shows the exact formula under the result.

Frequently asked questions
How do I convert denier to tex?
Divide denier by 9. For example, 90 denier is 10 tex.
What is decitex?
Decitex (dtex) is the mass in grams of 10,000 meters of yarn, so 1 tex is 10 dtex.
How many tex is 1 den?
1 den = 0.1111111111 tex, and 1 tex = 9.000000000 den.
