In dual dimensioned drawings, how are metric dimensions typically presented?

In dual dimensioned drawings, metric dimensions are typically presented in square brackets. This method provides a clear distinction between the two measurement systems used in the drawing—usually imperial and metric—allowing for easier interpretation by individuals familiar with either system. The square brackets effectively enclose the metric dimensions, helping users to identify them quickly and unambiguously. This visual cue supports clarity, especially on technical drawings where precision is paramount. Utilizing brackets avoids confusion that might arise from using similar formatting styles that could apply to dimensions, annotations, or other elements on the drawing.
