| Know before using | 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. | Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit. | CFDA states that it collects basic business information but does not audit, certify, or monitor the listed facilities, and that inclusion is not endorsement, recommendation, a quality guarantee, or CFDA membership. Verify identity, ownership, capabilities, materials, equipment, minimums, capacity, price, lead time, quality systems, labor and environmental practices, compliance, references, contracts, and product fit directly before selection. |

| What the source establishes | 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. | Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions. | CFDA publishes this as an open-access directory of United States fashion contract manufacturers with no registration required. The page supports sorting by service, product, category, and sample or production minimums and publishes an email route for manufacturers to add, update, or remove a listing. |
