About Denier To Tex Conversion Calculator

Denier is grams per 9000 metres and tex is grams per 1000 metres, so tex = denier / 9 and decitex = denier x 10 / 9. Denier per filament, the total denier divided by filament count, is the figure that governs fabric handle and softness in filament yarns.

Formulas

Denier and tex

tex = denier / 9; decitex = denier x 10 / 9; denier = tex x 9

Per filament

Denier per filament = total denier / filament count

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 6 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does denier per filament matter?

A 150 denier yarn with 48 filaments feels quite different from one with 144. Microfibre is generally defined as below 1 denier per filament, giving a soft, dense handle.

Which unit do standards prefer?

Decitex is the ISO preference for filament yarns because it gives convenient whole numbers, and tex for staple yarns. Denier persists commercially in synthetic filament trade.
