Translating the same fabric mass-per-area result between metric and U.S. customary listings
What the source establishes.
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.
The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface.
What this record does not prove.
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 reachable official source can verify identity, stated scope, and access. It cannot silently become an audit of workmanship, delivery, labor conditions, or suitability for your project.
A record that can age in public.
New checks are appended rather than replacing earlier states. The latest source review is due by July 16, 2027.
