Hey there, young gardener! Today we’re going to learn about measurements and how to change them from millimeters (which we can think of as “tiny meters”) to inches (which are a bit bigger and often used when measuring things like plants and garden tools).
So, why do we need to know about millimeters and inches? Well, when you’re gardening, it’s important to measure things like how deep to plant seeds or how far apart to put your flowers. Sometimes, different tools or seeds might use different types of measurements, so knowing how to change them can help you be a better gardener!
Now, let’s figure out how to convert 18 mm to inches.
First, we need to know that there are 25.4 millimeters in one inch. This is important because it helps us understand the relationship between these two measurements.
Next, to convert millimeters to inches, we can use the formula:
$$\text{inches} = \frac{\text{millimeters}}{25.4}$$
So, if we want to convert 18 mm to inches, we plug in the numbers:
$$\text{inches} = \frac{18}{25.4} \approx 0.7087$$
This means that 18 mm is about 0.71 inches when rounded.
Now, let’s think of some objects that are exactly equal to 18 mm (or 0.71 inches):
- The width of a pencil lead.
- The diameter of a small button.
- The size of a small cherry.
- The thickness of a thin book or notebook.
- The diameter of a coin (like a small penny).
- A large paperclip.
- The height of a standard Lego brick.
So next time you’re measuring your garden or figuring out spacing for your plants, remember this little tip about converting measurements! Happy gardening! 🌱
