The smallest division on a meter rule, also known as a meter stick, is typically 1 millimeter (mm). This means that each small line or marking on the meter rule represents a distance of 1 mm. The meter rule is divided into centimeters (cm) and millimeters (mm), with each centimeter divided into 10 millimeters. The smallest division of 1 mm allows for precise measurements to be taken using the meter rule.
