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.The record does not create product specifications, prove fit or manufacturability, select materials or construction settings, establish legal compliance, reproduce licensed standards, or replace qualified technical, production, quality, testing, sourcing, logistics, safety, compliance, and legal 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 documented-information, garment-measurement, stitch, and seam sources plus current U.S. FTC textile and care-labeling guidance; it discloses ISO 10013:2021's current review stage, and its working record makes organization-specific requirements, suppliers, evidence, issues, and approvals explicit.
