W × l

Direct yarn count, N

**= ………..............**
w × L

Where,

N denotes the yarn number or count,

W denotes the weight of the sample,

L denotes the length of the sample,

l denotes the unit length of the system,

w denotes the unit weight of the system.

**2. Indirect Count System:**

The count of yarn expresses the number of length units in one weight per unit. Higher the

**count**, finer the yarn. This system is generally uses for linen (wet spun),**cotton fibre**, worsted etc.
w × L

Indirect system, N

**= …………....….**
W × l

Where,

l indicates the unit length of the system,

L indicates the length of the sample,

w indicates the unit weight of the system,

W indicates the weight of the sample.
