When we’re working in gardening, sometimes we need to know how to change measurements from one system to another. For example, we often use millimeters (mm) for smaller measurements, but sometimes we want to convert those to inches.
To convert millimeters to inches, we can use a simple equation. We know that 1 inch is equal to 25.4 millimeters. So, to find out how many inches are in 84 mm, we can use this formula:
$$
\text{Inches} = \frac{\text{Millimeters}}{25.4}
$$
Plugging in our number, we get:
$$
\text{Inches} = \frac{84}{25.4} \approx 3.31 \text{ inches}
$$
This means that 84 mm is approximately 3.31 inches.
Here are seven objects that are exactly equal to 84 mm:
- A typical pencil (without the eraser)
- The width of a credit card
- The diameter of a standard tennis ball
- The length of a keychain charm
- The thickness of a small garden trowel
- The height of a small plant pot
- The length of a standard marble
