| 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. | Ribblr supplies the reading and publishing format, but each designer remains responsible for the pattern's math, sizing, instructions, testing, corrections, licence, and support. Interactive conveniences do not prove fit or technical accuracy. Pattern prices and available features vary, and following an ePattern depends on an account and continued platform access. | 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. |

| 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. | Ribblr's current ePattern manual documents line-by-line progress tracking, size-specific instructions, interactive charts, counters, attached media, stitch tutorials, unit handling, and left-hand display options. Its Ribbuild guidance says designers can create and test interactive crochet, knitting, and sewing patterns inside the platform. | 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. |
