When we talk about measurements, sometimes we use different units to understand sizes better. For example, millimeters (mm) and inches are two ways to measure length.
In gardening, you might want to know how tall a plant is or how wide a garden bed needs to be. If someone says a plant is 104 mm tall, and you want to know how tall that is in inches, we can do a little math!
To convert millimeters to inches, we use the following equation:
$$
\text{Inches} = \text{Millimeters} \div 25.4
$$
So in our case:
$$
\text{Inches} = 104 \text{ mm} \div 25.4 \approx 4.09 \text{ inches}
$$
This means that 104 mm is about 4.09 inches tall. It’s important in gardening to keep track of these measurements so we know how much space our plants need and how to take care of them!
Here are seven objects that are exactly equal to 104 mm:
- A standard pencil (length)
- A small ruler (length)
- A thicker paperback book (width)
- The height of a typical coffee cup
- The width of a smartphone
- A small garden trowel’s blade
- The depth of a small flower pot
Understanding these measurements helps you become a better gardener!
