Example;
 Denier of unknown count = Tex (known count) X 9
 Tex of unknown count = 0.1111 X Den or Jute count

5315

Metric

1000

9000

 Metric = 9000/Known Den count
 Denier = 5315/Known Ne
Conversion formula:
 Denier = 9 X Tex
 Ne X Denier = 0.5315
 Metric X Tex = 1000
 Tex X Ne = 590.5
 Ne = Metric X 0.5905
 Metric X Denier = 9000
 Tex = 34.45 X lb/ spyndle
