Know before usingAn 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.Patternmaking knowledge, controlled measurement files, production conventions, and sewn fit testing are still required. The software does not validate body measurements, ease, balance, grading rules, fabric behavior, construction, or product fit. The project currently labels its user wiki manual as needing updates, so confirm current commands and file behavior against the installed release and active support channels.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.

Source and review
What the source establishesThe guide cites current ISO sources for documented-information, garment-measurement, stitch, and seam boundaries plus current U.S. FTC textile and care-labeling guidance; it explicitly separates those authorities from product-specific technical and market decisions.The maintained Seamly2D repository identifies the application as GPLv3+ open-source patternmaking software for Windows, macOS, and Linux. It reads multi-size measurement files for standardized sizes and individual measurement files for custom-fit work, publishes downloadable builds and releases, and links an active website and user forum.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.
