What term describes a welding drawing that includes both inch units and metric units?

A welding drawing that includes both inch units and metric units is referred to as dual dimensioned. This term indicates that the drawing provides measurements in two different systems, allowing for greater flexibility and usability, especially in environments where both imperial and metric systems are common. Dual dimensioning is particularly advantageous in international projects or collaborations that involve stakeholders from different regions with distinct measurement preferences.

In contrast, single dimensioned drawings only use one measuring system, either metric or imperial. Drawings labeled as metric only utilize the metric system exclusively, while imperial only drawings rely solely on the imperial system. Thus, the correct choice succinctly captures the essence of incorporating both measurement types into a single drawing.
