| Know before using | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | 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. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. |

| What the source establishes | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | 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. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. |
