Know before usingThe brief does not approve a base pattern, size system, grade rule, pattern, file, provider, contract, classification, fee, fit, sample plan, production use, or intellectual-property position, and it does not replace qualified pattern, fit, CAD, employment, tax, privacy, and legal review.A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing.The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance.

Source and review
What the source establishesThe source-reviewed brief cites current U.S. Department of Labor task and title evidence, ISO documented-information, size-designation, body-table, and garment-measurement sources, first-party CAD exchange guidance, and one professional discovery route; it requires controlled inputs, explicit authority, receiver-tested files, sewn evidence, and acceptance records.YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems.The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls.
