Which type of dimension is measured in degrees, minutes, and seconds?

The type of dimension that is measured in degrees, minutes, and seconds is an angle dimension. This measurement system is used to express angles with precision, where degrees represent the main unit, and minutes and seconds provide further subdivisions for greater accuracy.

Angles can be critical in welding print reading as they dictate the orientation and relationship of components in a joint, ensuring that the weld meets design specifications. Understanding how to interpret angle dimensions is essential for achieving proper fit-up and alignment in welded assemblies.

In contrast, linear dimensions are typically measured in units of length, such as inches or millimeters, and do not involve angles. Radial dimensions refer specifically to distances from a center point to the outer edge of a circular feature, while diameter dimensions indicate the width of a circular feature directly. Thus, none of these alternatives involve angle measurement, thereby confirming that angle dimension is the appropriate choice.
