Yarn Twist (TPM)
Compute a yarn's twist in turns per meter (TPM) by dividing the number of turns by the length. Twist is what holds the fibers together and gives the yarn strength: too little produces a weak, fuzzy yarn; too much, a hard yarn prone to kinking. The direction (S or Z) and twist level define the yarn's character — knitting yarns are low-twist, crepe yarns high. Enter the number of turns and the length.

Torção do fio (TPM)
Um fio é feito de fibras curtas (ou filamentos) mantidas juntas pela torção — sem ela, as fibras escorregariam e o fio se desfaria. A torção, medida em voltas por metro (TPM), é um parâmetro crítico: pouca torção dá um fio macio, volumoso e felpudo, mas fraco (bom para tricô e felpudos); muita torção dá um fio fino, forte e liso, mas duro e com tendência a 'encaracolar' (kink) — levada ao extremo, cria o efeito crepe. O sentido também importa: torção 'S' (anti-horária) ou 'Z' (horária), e combiná-las em fios retorcidos equilibra o conjunto. A torção ideal escala com a finura do fio. Informe o número de voltas e o comprimento medido.

Yarn Count (Tex)
Compute a yarn's count in the Tex system, Tex = (mass in grams / length in meters) · 1000, i.e. the mass in grams of 1000 meters of the yarn. It is a 'direct' system (the higher the number, the thicker the yarn), standardized internationally. Tex links mass to length — the fundamental quantity defining yarn fineness and influencing strength, hand and fabric weight. Enter the mass and length of the yarn sample.

Tex ↔ Ne Conversion
Convert a yarn count from the Tex (direct) system to Ne (English count, indirect), Ne = 590.5/Tex. In the Ne system, unlike Tex, the higher the number the <em>finer</em> the yarn — so they are inversely proportional. Ne is traditional in cotton spinning. The conversion is essential to compare yarns specified in different systems. Enter the count in Tex.
