When we talk about measurements, sometimes we need to change from one unit to another. In this case, we are going to convert 15 millimeters (mm) into inches.
In gardening, knowing how to measure can help you understand how far apart to plant your seeds or how deep to dig your holes.
To make this conversion, we can use the fact that 1 inch is equal to 25.4 millimeters. To find out how many inches are in 15 mm, we can use the formula:
$$
\text{inches} = \frac{\text{millimeters}}{25.4}
$$
By putting our number in the formula, we can do the math:
$$
\text{inches} = \frac{15}{25.4} \approx 0.59
$$
So, 15 mm is approximately 0.59 inches. This is a little less than 3/4 of an inch!
Here are 7 objects that are exactly equal to 15 mm or about 0.59 inches:
- A large paperclip
- The diameter of a standard marble
- The thickness of a pencil tip
- A small button
- The width of a nickel coin
- The height of a Lego brick
- A grape
Knowing these measurements can really help you as you plan out your gardening project!
