Why the unit needs attention
Dimatex lists Troya mass in grams per linear metre, illustrating a real supplier convention. This is not the same unit as grams per square metre. The product is a reference for terminology, not a warp-knit comparison sample or evidence of current wholesale pricing.
Make the calculation explicit
For consistent measurements, grams per linear metre equals grams per square metre multiplied by width in metres. For example, a hypothetical 300 g/m² material at 1.40 m width has 420 grams per linear metre. This is an arithmetic example, not a Mingpin specification. Clarify whether the quoted mass includes all backing and adhesive.
Ask for the whole comparison basis
Our recommendation is to obtain measured width, face mass, total finished mass and their agreed tolerances. Compare equivalent finished products before asking which quote is lighter or cheaper. MPY0418 illustrates appearance only and has no mass stated in this article. Request its actual technical sheet before using it in a backed-fabric cost comparison.
