In gardening, sometimes we need to use different units of measurement to help us understand the size of plants, tools, or spaces in our garden. One common unit we use in the United States is **inches**, while many other countries, including ours, often use **centimeters** (cm).

To convert **centimeters** to **inches**, we can use a simple math formula. We know that there are about **2.54 centimeters** in **1 inch**. So, if we want to find out how many inches are in **18 centimeters**, we can use the equation:

$$

\text{Inches} = \frac{\text{Centimeters}}{2.54}

$$

Now, plugging in our number:

$$

\text{Inches} = \frac{18}{2.54} \approx 7.09 \text{ inches}

$$

This means that **18 centimeters is approximately 7.09 inches**!

To help you visualize this, here are **7 objects** that are exactly the same length as **18 cm**:

- A medium-sized
**pencil**. - A
**smartphone**lengthwise (but not including the thickness). - A standard
**ruler**(some rulers have marks for centimeters). - A
**DVD case**height. - A
**book**that is slightly smaller than a standard hardcover. - The width of a
**food can**(like a soup can). - A typical
**carrot**(the length of an average carrot).

Remember, being able to convert **centimeters** to **inches** helps us understand the sizes of different things in our gardening adventures!
