| Know before using | This is a length-unit translation reference. It does not identify the measured feature; select, approve, or change a seam allowance; establish a universal fraction; interpret an unstated cutting or stitching line; or replace the exact pattern version, controlled specification, material and seam evidence, sample, production method, equipment, tolerance, or release authority. | Free access does not grant commercial reproduction or sale rights; uses beyond one personal copy must be resolved with the designer or author. Knitty says it tries to avoid errors but disclaims responsibility for pattern and technique inaccuracies. Check the live page for corrections, verify gauge and measurements, and confirm permission before any commercial use. | The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. | 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. |

| What the source establishes | NIST states that 10 millimetres equal 1 centimetre and that one inch is exactly 25.4 millimetres. The tool uses those relationships, displays rounded equivalents, exposes the size difference to the nearest 1/16 inch when converting to inches, and preserves valid value, source-unit, and target-unit state in the URL. | Knitty currently publishes web-only editorial issues containing original knitting and crochet patterns and articles. Its legal page states that patterns are free for one person's personal use, identifies each designer or author as the copyright holder, and explains that verified pattern corrections are posted in bright pink on the pattern page. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. | 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. |
