| 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. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | 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. | A foundational library, not yet an exhaustive stitch encyclopedia. |

| 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. | The individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | 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. | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. |
