Easily convert thread count with our Thread Count Converter. Learn formulas, conversion charts, and FAQs for TPI, TPC, TPM, and yarn counts like Nm to Ne.
Thread count plays a crucial role in determining fabric quality, durability, and comfort. Whether you're working with textiles, bed linens, or yarn manufacturing, knowing how to convert thread count across different units like inches, centimeters, and meters is essential.
Our Thread Count Converter is designed to help users effortlessly calculate thread count and convert it between various measurement systems. In this guide, we will explore everything about thread count conversion, including formulas, tables, and FAQs to ensure complete understanding.
Thread count refers to the number of threads woven into one square inch or square centimeter of fabric. It includes both horizontal (weft) and vertical (warp) threads. A higher thread count usually means a finer, softer, and more durable fabric, but other factors like yarn quality and weave type also affect the final feel of the fabric.
The formula for thread count is:
Thread Count (TPI) = Number of Warp Threads + Number of Weft Threads per inch
For metric conversions, the formulas are:
If the fabric is multi-ply, you need to divide the thread count by the ply number to get the actual count per yarn.
Below is a simple thread count conversion table for quick reference:
Threads per Inch (TPI) | Threads per Centimeter (TPC) | Threads per Meter (TPM) |
---|---|---|
50 | 19.69 | 1969 |
100 | 39.37 | 3937 |
200 | 78.74 | 7874 |
400 | 157.48 | 15748 |
600 | 236.22 | 23622 |
To convert yarn count between different numbering systems, use these formulas:
The perfect thread count depends on fabric type and intended use.
Not necessarily. A 1000 thread count sheet may not be significantly better than a 400 thread count sheet if the yarn quality is poor. Manufacturers sometimes twist multiple threads together to artificially inflate the count without improving the fabric’s quality.
Understanding thread count and how to convert it ensures better decisions when selecting fabrics, yarns, and textiles. Our Thread Count Converter simplifies the process, making it easy for anyone to perform accurate conversions. Whether you are a textile expert, manufacturer, or just someone shopping for high-quality fabric, knowing the correct thread count ensures the best choice.
Use the formula Ne = Nm ÷ 1.69.
TPI (Threads per Inch) is used in imperial measurement, while TPM (Threads per Meter) is used in the metric system.
Not always. A high-quality 400 TPI fabric can be better than a poorly constructed 1000 TPI fabric.
Use the formula Ne = 5315 ÷ Denier to find the equivalent count.
