Convert Denier to Kilograms per Metre (den to kg/m)
1 denier (den) = 1.111111111 × 10⁻⁷ kilograms per metre (kg/m). 1 kg/m = 9000000 den. Example: 15 den = 15 × 1.111111111 × 10⁻⁷ = 0.000001666666667 kg/m.

How to Convert Denier to Kilogram per Metre
- 1 den = 1.111111111 × 10⁻⁷ kg/m
- 1 kg/m = 9000000 den
- Example: convert 15 den to kg/m: 15 den = 15 × 1.111111111 × 10⁻⁷ kg/m = 0.000001666666667 kg/m
Formula
kg/m = den × 1.111111111111 × 10⁻⁷
or kg/m = den ÷ 9000000
Derivation from SI units:
- 1 den = 1 g per 9000 m = 1/9 tex ≈ 1.111 × 10⁻⁷ kg/m (exact)
- The coherent SI unit of linear density: mass in kilograms per metre of length.
Both units are defined exactly, so the factor is exact. Denier definition: denier; Kilogram per Metre definition: kilogram per metre.
Worked examples
- A reading of 40 den converts to 0.000004444444444 kg/m.
40 den × 1.111111111 × 10⁻⁷ = 0.000004444444444 kg/m - A value of 150 den is 0.00001666666667 kg/m.
150 den × 1.111111111 × 10⁻⁷ = 0.00001666666667 kg/m

Where it's used
Denier are used for hosiery and tights (for example 15–40 den), while kilograms per metre appear in ropes, cables and heavy tows. Both measure yarn count (linear density of yarns and fibres), so the conversion is a fixed factor.

Frequently asked questions
How many kilograms per metre are in 1 denier?
1 den = 1.111111111 × 10⁻⁷ kg/m.
How do I convert denier to kilograms per metre?
Multiply the value in den by 1.111111111 × 10⁻⁷, or divide it by 9000000. For example, 15 den × 1.111111111 × 10⁻⁷ = 0.000001666666667 kg/m.
Is the den to kg/m conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
