What is the assumption about units in metric drawings?

In metric drawings, the standard assumption is that dimensions are expressed in meters unless specified otherwise. This convention aligns with the metric system, where the meter serves as the fundamental unit of length. Noting this helps ensure clarity and consistency in communication, especially in fields like architecture and engineering, where precise measurements are essential.

When no unit is explicitly stated on a drawing, it is a standard practice to interpret the dimensions in meters. This avoids confusion that might arise from using other units, allowing professionals and stakeholders to work with an understood baseline across international projects. As a result, the interpretation of measurements as being in meters is crucial for accurate planning and execution.
