## Measuring Centimeters with a Ruler

When it comes to measuring lengths in centimeters, using a ruler is the most precise method. A ruler is designed with markings that represent centimeters and millimeters, allowing for accurate measurements.

Each centimeter on a ruler is divided into 10 equal parts, which are known as millimeters. By aligning an object with the appropriate markings on the ruler, you can determine its length in centimeters with great accuracy.

### Using a Ruler for Measurements

Here’s a step-by-step guide on how to measure centimeters using a ruler:

1. Place the ruler along the length of the object you want to measure.
2. Align one end of the object with the zero mark on the ruler.
3. Observe the marking on the ruler that aligns with the other end of the object.
4. Count the number of centimeter marks between the zero mark and the observed marking to determine the length in centimeters.

For example, if the end of an object aligns with the 5-centimeter mark and there are 3 marks between the zero and the observed marking, the length of the object is 5 + 3 = 8 centimeters.

Using a ruler allows for precise measurements and is especially useful when dealing with small lengths like centimeters.
