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.

Yarn twist (TPM)
A yarn is made of short fibers (or filaments) held together by twist — without it, the fibers would slip apart and the yarn would fall apart. Twist, measured in turns per meter (TPM), is a critical parameter: low twist gives a soft, bulky, fuzzy yarn, but a weak one (good for knitting and terry fabrics); high twist gives a fine, strong, smooth yarn, but a hard one with a tendency to 'snarl' (kink) — taken to the extreme, it creates the crepe effect. The direction matters too: 'S' twist (counterclockwise) or 'Z' twist (clockwise), and combining them in plied yarns balances the assembly. The ideal twist level scales with the fineness of the yarn. Enter the number of turns and the measured length.

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.
Paper Tensile Index
Compute the paper tensile index, index = tensile strength (N/m) / grammage (g/m²), in N·m/g, normalizing the strength by the grammage to allow comparing papers of different weights. It is one of the most important mechanical properties, linked to fiber strength, inter-fiber bonding and refining. Packaging and sack papers require a high tensile index. Enter the tensile strength and the grammage.
Allowable Geosynthetic Strength
Calculate the allowable (design) tensile strength of a geosynthetic, T_adm = T_ult ÷ (RF_cr·RF_id·RF_cd), from the ultimate strength T_ult (kN/m, from a short-term tensile test) and the reduction factors for creep RF_cr, installation damage RF_id and chemical/biological degradation RF_cd. Geosynthetics (geotextiles, geogrids, geomembranes) used as soil REINFORCEMENT in walls, slopes and embankments on soft soils must work for decades, and their design strength is far below the lab value from quick tests. The reduction factors discount: CREEP (polymers under constant load deform and lose strength over time, RF_cr typically 2-5, the largest factor); INSTALLATION DAMAGE (compacting gravel fill over the geosynthetic causes abrasion and punctures, RF_id ~1.1-2); and chemical/biological DEGRADATION over the service life (RF_cd ~1.1-2). Their product can reduce the allowable strength to 20-40% of the ultimate. This is the basis of designing any reinforced-soil structure, and underestimating the reduction factors (overestimating strength) is a cause of reinforced wall and slope failures. Enter the ultimate strength and the three reduction factors.
