| Know before using | The record does not validate every size or user, prove bulk conformity, prescribe universal defect classes or AQL, replace testing or inspection, or establish compliance. | The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. |

| What the source establishes | The record applies version and lot controls from textile testing plus current ISO and ASQ acceptance-sampling boundaries to separate sample approval from bulk release. | The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. |
