The Straightforward Conversion Formula
The conversion from centimeters to inches is a simple process, and it involves a basic formula that you can easily remember. Here’s how you can do it:
\[ \begin{equation*} 24\text{ cm} \cdot \frac{1\text{ inch}}{2.54\text{ cm}} \approx 9.4488\text{ inches} \,. \end{equation*} \]
Understanding the Conversion Factor
In the formula above, the conversion factor of 1 inch to 2.54 centimeters is a critical element. This factor is the key to accurately translating measurements between the metric and imperial systems. By dividing the given length in centimeters by this factor, you get the equivalent length in inches.
Practical Application
Let’s apply this formula to our specific case:
\[ \begin{align*} 24\text{ cm} \cdot \frac{1\text{ inch}}{2.54\text{ cm}} & \approx 9.4488\text{ inches} \,. \end{align*} \]
So, 24 centimeters is approximately equal to 9.45 inches. It’s a straightforward calculation, and with practice, you’ll be able to perform such conversions effortlessly.
