| Know before using | This is a unit-translation reference. It does not 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. | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. |

| What the source establishes | NIST states that one inch is exactly 25.4 millimetres, and the SI decimal relationship makes one centimetre equal to 10 millimetres. The tool uses those factors, 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 official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. |
