Khadi Count vs Cotton Count: A Simple Conversion Guide for Textile Learners
In textile discussions, the word count appears very often. We speak of 20s cotton, 40s cotton, 80 count yarn, fine-count muslin, sari yarn and hand-spun khadi yarn. The basic idea is simple: yarn count tells us whether a yarn is coarse or fine.
However, the difficulty begins when two different count systems use the same word but different measuring units. This happens when we compare the khadi count described in charkha literature with the English cotton count, commonly written as Ne. Both systems are indirect count systems, but they are not numerically equal.
Main idea: The khadi count described in the Charkha Manual is based on hanks of 1000 metres per kilogram. Cotton count, or English cotton count, is based on hanks of 840 yards per pound. Because the units are different, the same yarn will have different numerical counts in the two systems.

What Is Yarn Count?
Yarn count is a numerical way of expressing yarn fineness. A thick yarn, such as one used in canvas or heavy sheeting, has a lower indirect count. A finer yarn, such as one used in voile, fine sari fabric or muslin, has a higher indirect count.
In many spun yarn systems, the count is an indirect measure. This means that the count increases as the yarn becomes finer. A higher number therefore represents a longer length of yarn in the same unit weight.
This is different from direct systems such as tex or denier, where a higher number means a heavier or thicker yarn. This distinction is important because textile learners often confuse indirect and direct numbering systems.

What Is Khadi Count?
The Charkha Manual describes a hank as a bundle of 1000 metres of yarn. It then defines the count of yarn as the number of such hanks present in 1 kilogram of yarn.
Using this definition, if 1 kg of yarn contains 30 hanks of 1000 metres each, the yarn is called 30 count yarn. If 1 kg contains 100 such hanks, it is called 100 count yarn. This is practically the same numerical form as the metric count system, commonly written as Nm.
\[ \text{Khadi Count} = \frac{\text{Length of yarn in metres}}{1000 \times \text{Weight in kg}} \]
So, 40 khadi count means 40,000 metres of yarn in 1 kg. In simpler words, it means 40 kilometres of yarn per kilogram. Similarly, 100 khadi count means 100 kilometres of yarn per kilogram.
What Is Cotton Count?
Cotton count is usually written as Ne, NeC, or simply as cotton count. In this system, one hank is equal to 840 yards, and the count is the number of such hanks present in 1 pound of yarn.
For example, if 1 pound of yarn contains 40 hanks of 840 yards each, the yarn is called 40s cotton count or 40 Ne. This system is still widely used in cotton spinning, weaving, garment sourcing and fabric specifications.
\[ Ne = \frac{\text{Length of yarn in yards}}{840 \times \text{Weight in pounds}} \]
Like khadi count, cotton count is also an indirect count system. A higher Ne value means a finer yarn. For example, 60s cotton is finer than 40s cotton, and 100s cotton is finer than 60s cotton.
Why Conversion Is Needed
The confusion starts because both systems use the word count, and both systems increase as the yarn becomes finer. But one system is based on metres and kilograms, while the other is based on yards and pounds.
Therefore, 80 khadi count is not the same as 80 Ne. If we read a khadi text and directly compare its count with cotton count, we may overestimate or misunderstand the actual fineness of the yarn.
This matters especially when we interpret traditional khadi descriptions. A text may say that ordinary cloth uses 30 to 50 count yarn, sari yarn uses 80 to 100 count yarn, and muslin uses 120 count or more. These numbers make better technical sense when we convert them into the more familiar cotton count system.
Deriving the Conversion
To compare khadi count and cotton count, both must be expressed in the same unit. The easiest common unit is metres per kilogram.
In cotton count, one hank is 840 yards. Since 1 yard is equal to 0.9144 metre, the length of one cotton hank becomes:
\[ 840 \times 0.9144 = 768.096 \text{ metres} \]
Also, 1 pound is equal to 0.45359237 kg. Therefore, 1 Ne represents:
\[ 1Ne = \frac{768.096}{0.45359237} \]
\[ 1Ne = 1693.36 \text{ metres per kg} \]
In khadi count, 1 count means 1000 metres per kg. Therefore, to convert cotton count into khadi count, we divide 1693.36 by 1000.
\[ 1Ne = 1.693 \text{ khadi count} \]
Final Conversion Formula
The conversion between cotton count and khadi count is therefore quite simple. To convert cotton count into khadi count, multiply by 1.693.
\[ \boxed{\text{Khadi Count} \approx 1.693 \times Ne} \]
To convert khadi count back into cotton count, divide by 1.693. This gives the approximate equivalent English cotton count.
\[ \boxed{Ne \approx \frac{\text{Khadi Count}}{1.693}} \]
\[ \boxed{Ne \approx 0.5905 \times \text{Khadi Count}} \]

Conversion Examples
The following table shows how common cotton counts convert into approximate khadi counts. This is useful when a cotton yarn specification has to be understood in the khadi or metric count sense.
| Cotton Count, Ne | Calculation | Approximate Khadi Count |
|---|---|---|
| 20 Ne | \(20 \times 1.693\) | 33.9 |
| 30 Ne | \(30 \times 1.693\) | 50.8 |
| 40 Ne | \(40 \times 1.693\) | 67.7 |
| 50 Ne | \(50 \times 1.693\) | 84.7 |
| 60 Ne | \(60 \times 1.693\) | 101.6 |
| 80 Ne | \(80 \times 1.693\) | 135.5 |
| 100 Ne | \(100 \times 1.693\) | 169.3 |
The next table shows the reverse conversion. This is more useful when reading khadi literature and converting the given khadi count into the more familiar English cotton count.
| Khadi Count | Calculation | Approximate Cotton Count, Ne |
|---|---|---|
| 30 | \(30 \div 1.693\) | 17.7 Ne |
| 40 | \(40 \div 1.693\) | 23.6 Ne |
| 50 | \(50 \div 1.693\) | 29.5 Ne |
| 80 | \(80 \div 1.693\) | 47.2 Ne |
| 100 | \(100 \div 1.693\) | 59.1 Ne |
| 120 | \(120 \div 1.693\) | 70.9 Ne |
| 150 | \(150 \div 1.693\) | 88.6 Ne |
Interpreting the Charkha Manual
The Charkha Manual mentions that yarn of 30 to 50 count is commonly spun on the box charkha and is required for most day-to-day cloth. If this is read as khadi count, it corresponds approximately to 18s to 30s cotton count.
\[ 30 \text{ khadi count} \approx 17.7 Ne \]
\[ 50 \text{ khadi count} \approx 29.5 Ne \]
This range makes practical sense. It represents yarn suitable for ordinary cloth, where the yarn does not have to be extremely fine but must be strong and usable for daily wear.
The manual also mentions that sari yarn is made from finer yarn of 80 to 100 count. When converted into cotton count, this becomes approximately 47s to 59s Ne.
\[ 80 \text{ khadi count} \approx 47.2 Ne \]
\[ 100 \text{ khadi count} \approx 59.1 Ne \]
This also fits textile logic. A sari generally requires a finer, smoother and more flexible yarn than ordinary coarse cloth. The yarn must help the fabric achieve better drape, surface appearance and handle.
The manual further mentions that still finer yarn of 120 count or more is used for muslin. In cotton count terms, 120 khadi count is approximately 71 Ne.
\[ 120 \text{ khadi count} \approx 70.9 Ne \]
This helps us understand the statement more accurately. Muslin requires fine yarn, but if the number is from the khadi or metric count system, it should not be mistaken for 120 Ne cotton count.

A Practical Memory Rule
The easiest way to remember the relationship is this: khadi count is about 1.7 times cotton count for the same yarn fineness. Therefore, a 30 Ne cotton yarn is roughly 51 khadi count, and a 60 Ne cotton yarn is roughly 102 khadi count.
The reverse rule is also useful. Cotton count is about 59 percent of khadi count. Therefore, 100 khadi count is roughly 59 Ne, and 120 khadi count is roughly 71 Ne.
Simple memory rule: Multiply Ne by 1.693 to get khadi count. Divide khadi count by 1.693 to get Ne.
Quick Reference Table
| Khadi Description | Khadi Count Range | Approximate Cotton Count Range | Practical Meaning |
|---|---|---|---|
| Day-to-day cloth yarn | 30 to 50 | 18s to 30s Ne | Medium to coarser yarn suitable for ordinary cloth |
| Sari yarn | 80 to 100 | 47s to 59s Ne | Finer yarn suitable for better drape and handle |
| Muslin yarn | 120 and above | 71s Ne and above | Fine yarn used for lightweight and delicate fabric |
Conclusion
Khadi count and cotton count both describe yarn fineness, but they do not use the same measuring base. The khadi count described in the Charkha Manual uses 1000 metre hanks per kilogram, while English cotton count uses 840 yard hanks per pound.
Because of this difference, the same yarn will show a higher number in khadi count than in cotton count. The correct relationship is:
\[ \text{Khadi Count} \approx 1.693 \times Ne \]
\[ Ne \approx 0.5905 \times \text{Khadi Count} \]
This conversion helps us read khadi literature more accurately. It also prevents the common mistake of treating 80 khadi count as 80 Ne, or 120 khadi count as 120 Ne. Once the conversion is understood, the yarn ranges mentioned for daily cloth, sari and muslin become much clearer.
