A uniform metre rule is

a measuring instrument that is one meter long and has divisions at every millimeter, allowing for precise measurements of length. It is usually made of wood or metal and has markings that indicate the length in centimeters and millimeters. The uniformity of the rule ensures that each unit of measurement is consistently sized and accurate. It is commonly used in physics experiments, construction projects, and in classrooms to teach the concept of measurement.

A uniform meter rule, also known as a meter stick or a meter scale, is a measuring tool used to measure length or distance. It is typically made of a long, thin strip of metal or plastic, usually one meter in length. The meter rule is divided into centimeters (cm) and millimeters (mm) and is marked with a series of evenly spaced lines that represent these units of measurement. The markings are usually labeled at every centimeter and often have additional markings at every millimeter. The meter rule is a versatile tool used in various fields such as physics, engineering, and construction, to measure objects or distances with precision.
