What thickness measurement is commonly referred to regarding metal caskets?

The thickness of metal caskets is commonly referred to in terms of "gauge." The gauge system is a standardized measurement that denotes the thickness of the metal used in the casket’s construction. In this system, a lower gauge number indicates a thicker material; for instance, a 20-gauge metal is thicker than a 22-gauge. This measurement is crucial in the industry as it helps inform consumers about the durability and quality of the casket.

The terms inches or millimeters are not standard in this context. Inches may describe dimensions in length or width, while millimeters are more precise but are less common in the mortuary industry regarding casket thickness. Liters pertain to volume and are irrelevant when discussing the thickness of metal used in caskets. Therefore, gauge is the appropriate term that reflects the established practices within the field of mortuary administration.
