Hey there! Today, we’re going to learn how to change a measurement from millimeters to inches. This is super useful, especially if you’re measuring things for your garden!
Millimeters (mm) are a tiny unit of measurement. To make them easier to understand, we often change them into inches, which are a bit bigger and more commonly used in places like the United States.
To convert 169 millimeters to inches, we can use a special number. Did you know that 1 inch is equal to 25.4 millimeters? That means when we want to find out how many inches are in 169 mm, we need to divide by 25.4.
So, we can write it like this:
$$
\text{Inches} = \frac{169 \, \text{mm}}{25.4}
$$
When you do the math, you find that:
$$
\text{Inches} \approx 6.65
$$
This means that 169 mm is roughly 6.65 inches!
Why Is This Important in Gardening?
Knowing how to convert measurements can help you with your gardening! For example, many seeds come with instructions that list how deep to plant them in inches. If your seed packet says to plant seeds 6.65 inches deep, you can remember that this is about 169 mm. This will help you make sure your plants grow healthy and strong!
