Steel rules are typically graduated in the English (Inch) system and the Metric system.
Steel rules, also known as measuring rulers or scales, are essential tools used for precise measurements in various fields, from engineering and manufacturing to woodworking and drafting. These rules are marked with graduations representing specific units of length. Commonly, steel rules feature both the English (Inch) system and the Metric system, often displayed on opposite sides or edges of the rule, allowing users to easily switch between the two measurement standards. This dual graduation makes steel rules versatile and adaptable for use in a wide range of applications, regardless of the measurement system preferred or required.
-
English (Inch) System: This system is based on the inch as the fundamental unit, with further divisions into fractions of an inch (e.g., 1/2, 1/4, 1/8, 1/16, 1/32, and 1/64 inches). It is widely used in the United States and some other countries.
-
Metric System: This system is based on the meter as the fundamental unit, with decimal subdivisions such as millimeters (mm), centimeters (cm), and decimeters (dm). It is the standard measurement system used in most countries around the world.
Having both systems on a single steel rule eliminates the need for carrying separate measuring tools and simplifies conversions between the two systems. The precise graduations on a steel rule ensure accurate measurements, making it an indispensable tool for professionals and hobbyists alike.
