Know before usingA shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval.An orientation rather than a completed product record; it does not supply a universal format, licensed standard content, measurements, tolerances, construction settings, labels, approvals, compliance conclusion, or product-release authority.ATA's completeness language is an operator claim. Buyer-guide or member-directory inclusion does not establish a complete market map, current production capability, capacity, ownership, certification, product suitability, commercial terms, or project fit. Verify the actual company, site, product, documents, samples, and terms directly.

Source and review
What the source establishesRechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled.The guide cites published ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it discloses that ISO 10013:2021's 2026 systematic review is at close-of-review stage and separates every cited authority from product-specific technical and market decisions.ATA's current sourcing page links buyer's guides covering suppliers and products, a searchable member directory, and other association sourcing tools for the advanced and specialty-textile supply chain. ATA's own directory overview describes company listings and product showcases as ways for fabricators to find products and potential partners.
