"scale ruler"的定义和意义

What is a "scale ruler"?

A scale ruler is a tool used to measure and draw objects at a smaller or larger scale than their actual size. It has multiple scales marked on its surface, allowing users to convert measurements from a scaled drawing to real-world dimensions. The most common scales on a scale ruler include ratios like 1:10, 1:50, or 1:100. Scale rulers are widely used in fields such as architecture, engineering, and design to create and read blueprints, technical drawings, and maps accurately. They help ensure that drawings are proportionate and can be translated into real-world measurements.
