Turns per Centimeter to Turns per Meter (TPcm to TPM)
1 turn per centimetre (TPcm) = 100 turns per metre (TPM). 1 TPM = 0.01 TPcm. Example: 15 TPcm = 15 × 100 = 1500 TPM.

How to Convert Turn per Centimeter to Turn per Meter
- 1 TPcm = 100 TPM
- 1 TPM = 0.01 TPcm
- Example: convert 15 TPcm to TPM: 15 TPcm = 15 × 100 TPM = 1500 TPM
Formula
TPM = TPcm × 100
Derivation from SI units:
- 1 turn per cm = 100 turns per metre
- The SI-based unit of twist: complete turns of the yarn about its axis per metre of length.
Both units are defined exactly, so the factor is exact. Turn per Centimeter definition: turn per centimetre; Turn per Meter definition: turn per metre.
Worked examples
- A reading of 4 TPcm converts to 400 TPM.
4 TPcm × 100 = 400 TPM - A value of 8 TPcm is 800 TPM.
8 TPcm × 100 = 800 TPM

Where it's used
Turns per Centimeter are used for filament and ply twist, while turns per metre appear in spinning and twisting specifications in metric mills. Both measure yarn twist (turns per unit length), so the conversion is a fixed factor.
Turn per Centimeter to other yarn twist units
| Conversion | 1 TPcm equals |
|---|---|
| turn per centimetre to turn per metre | 100 TPM |
| turn per centimetre to turn per inch | 2.54 TPI |
| turn per centimetre to turn per foot | 30.48 TPF |
Frequently asked questions
