🧵 Yarn Count Calculator

A simple educational web application for calculating yarn count from given length and weight parameters.

Designed for 2nd Year Textile Engineering students.

Features

The application calculates yarn count using four common yarn count systems:

1. English Cotton Count (Ne)
2. Metric Count (Nm)
3. Tex
4. Denier

Students select the count system, enter the length and weight, and the application calculates the yarn count.

Yarn Count Systems

1. English Cotton Count (Ne)

English Cotton Count is an indirect yarn numbering system.

Formula:

Ne = Length (yards) / [840 × Weight (lb)]

A higher Ne indicates a finer yarn.

---

2. Metric Count (Nm)

Metric Count is an indirect yarn numbering system.

Formula:

Nm = Length (meters) / Weight (kg)

A higher Nm indicates a finer yarn.

---

3. Tex

Tex is a direct yarn numbering system.

Formula:

Tex = Weight (grams) / Length (km)

A higher Tex indicates a coarser/heavier yarn.

---

4. Denier

Denier is a direct yarn numbering system.

Formula:

Denier = Weight (grams) × 9000 / Length (meters)

A higher Denier indicates a coarser/heavier yarn.
