Do you ever wonder how big things are in different measurements? Sometimes we use millimeters (mm) and other times we use inches. Imagine you’re getting ready to plant a garden and want to know how long something is!
In this case, we have 446 millimeters. To find out how many inches that is, we can use a simple formula. There are about 25.4 millimeters in an inch. To change millimeters to inches, we can divide the millimeter number by 25.4.
So, we use the equation:
$$
\text{Inches} = \frac{446 \text{ mm}}{25.4}
$$
When you do the math, you find out that 446 mm is approximately 17.6 inches. That’s just under a foot and a half!
Now, if you want to see things that might be about that size, here are 7 objects that are exactly 17.6 inches long:
- A standard ruler (the long ones used in school)
- A small garden trowel used to dig up soil
- A kitchen knife (the blade part)
- A regular-sized notebook
- A medium-sized potted plant, like a small tomato plant
- A bicycle handlebar on a smaller bike
- A small backpack strap
Next time you’re in your garden, you can measure items and see how they compare to 446 mm or 17.6 inches! Understanding different measurements helps us know what we need for our plants and garden tools. Happy gardening!
