What are the uses of steel rule?

A steel rule is a simple measuring instrument that is used for measuring distances and ruling straight lines. It is used in diverse fields, such as geometry, technical drawing, engineering and construction.

The steel rule is a very common measuring tool. According to the Encyclopedia of Alternative Energy, flat steels rule are generally 6 or 12 inches long. These steel rules can either be flexible or rigid; their widths determine the accuracy of measurement.

Thin rules are more accurate for measurements because division marks are closer to the object of measurement. A steel rule is used in geometry, technical drawing, engineering and building to measure distances and rule straight lines.
