It is use to measure distance
A meter rule.
Measurement of length.
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.
0.5mm
If the calibration starts from the edge of the stick then it is a meter rule Basically "0" starting from the edge And if it is a meter ruler ,there is like half inch of empty space before 0
0.5
1 place the scale in contact with the object along its length starting from 0. if the zero mark is not clear use any other full mark of the scale. 2 your eye must be exactly in front of the point where the measurement is to be taken.
Balancing the meter rule on the wedge edge-wise ensures that the weight of the meter rule is evenly distributed on both sides, leading to a stable and accurate reading. Placing it edgewise helps minimize the effect of friction and other external forces that may affect the balance of the rule.
Measuring anything up to a metre (meter in USA); drawing straight lines. Rule is the "proper" word for what most of us call a ruler.
Two methods: 1. mark a point on the circumference of the round object; put a mark on the floor; line up the marks and roll the object along the floor until the mark retouches the floor; use the meter rule to find the distance between the marks on the floor. 2. measure the diameter of the round object using the meter rule and multiply it by π (pi ≈ 3.14159)

I would use a measuring tape because it is easier to wrap it around a baby's head.
