There are many yarn count systems in the world, so here are a few that are used for coned yarn with industrial standards. Find how to calculate conversions of yarn count at the bottom of this page.

**Numero metric count **

The numero metric yarn count ‘**Nm**’ is used the most for industrial yarn in Europe and Asia, which is why we chose to mainly work with this. This metric numbering system (Nm) indicates ‘number of 1000m (or 1 km) of yarn per 1kg weight’. The metric count is written count/ply.

A few examples:

- Nm30 = 30 km of yarn weighs 1 kilogram. These yarns have the same yarn weight:

- Nm30 is only 1 end of yarn
- Nm60/2 is two ends of yarn, both Nm60.
- Nm120/4 is 4 ends of yarn, each Nm120.

- Nm6 = 6 kilometer of yarn weighs 1 kilogram. These yarns have the same yarn weight:
- Nm6 is only 1 end of yarn
- Nm12/2 is two ends of yarn, both Nm12
- Nm24/4 is four ends of yarn, each Nm24

- Nm8 = 8 kilometer of yarn weighs 1 kilogram. These yarns have the same yarn weight:

- Nm8 is only 1 end of yarn.
- Nm16/2 is two ends of yarn, both Nm16
- Nm32/4 is four ends of yarn, each Nm32

**Tex**

Tex indicates ‘how many grams of yarn per 1000m’.

Example:

- 30Tex means that 30 grams of yarn are 1000m long. Decitex (dTex) indicates how many grams of yarn per 10000m.

**Denier**

Denier (DEN) is often used for nylon stockings and tights. It indicates ‘how many grams of yarn per 9000m’.

Example:

- 30D means that 30 grams of yarn are 9000m long.

*For Nm, dtex and DEN applies: ‘The higher the number, the finer the yarn’.*

**Imperial yarn counts**

Cotton count, worsted count and linen count are imperial counts, meaning they are measured in yards and pounds.

Count system |
Definition |

Cotton count (cc or ne) | 840 yards/pound |

Worsted count (wc) | 560 yards/pound |

Linen count (lea or nel) | 300 yards/pound |

Imperial counts (cc/wc/lea) are usually written as ply/count, for examle 'wc2/12' or 'cc2/8'. To work out the yards per pounds for a specific yarn count, you multiply the yarn count by the number of yards in the definition, then divide by the ply. For example:

wc2/12 = (12 x 560) / 2 = 3360 yards/pound

cc2/8 = (8 x 840) / 2 = 3360 yards/pound

**Converting meters/kilogram and yards/pound**

With all these different yarn counts being used, it's helpful to be able to convert yarn counts. You can calculate as follows:

yard/pound to meter/kilogram: multiply by 2.016

meter/kilogram to yard/pound: multiply by 0.495

For example:

3360 yards/pound x 2.016 = 6777 meters/kilometer = Nm6.8

8000 meter/kilogram x 0.495 = 3960 yards/pound = wc2/14 or cc2/9 for 2 ply yarns

As the machine works best with industrial spun yarn on cones, you can compare this industrial used yarn count to a light fingering or 2 ply hand knitting yarn (needle size around 2mm).

**Note**: Hand knitting yarns are almost always not suited for Kniterate.
