The Conversion Process: From Centimeters to Inches



To convert 24.5 centimeters to inches, we need to use the conversion factor: 1 inch = 2.54 centimeters. We can set up a simple equation:

```
x inches = 24.5 cm (1 inch / 2.54 cm)
```

Notice how we've multiplied 24.5 cm by a fraction equal to 1. This fraction, (1 inch / 2.54 cm), is our conversion factor. The centimeters cancel out, leaving us with inches. Now, let's do the math:

```
x inches = 24.5 cm / 2.54 cm/inch
x inches ≈ 9.6456 inches
```

Therefore, 24.5 centimeters is approximately equal to 9.65 inches (rounding to two decimal places for practical purposes).
