20.4 Centimeters to Inches equals 8.0315 in.

To convert 20.4 cm to inches, you need to understand the basic conversion factor between centimeters and inches. The conversion factor commonly used is 1 inch equals 2.54 centimeters. Thus, to convert centimeters into inches, you divide the number of centimeters by 2.54. This gives you the equivalent length in inches because you're converting a smaller unit (centimeter) to a larger unit (inch), and hence, the number of units decreases.

Applying this conversion factor to 20.4 cm:

\([20.4 \, \text{cm} \div 2.54 \, \text{cm/inch} = 8.03149606 \, \text{inches}]\)

For practical purposes, this value is often rounded to two decimal places, making the length approximately 8.03 inches. This conversion is quite straightforward once you remember the specific unit equivalence of 1 inch to 2.54 cm. By doing so, you're essentially scaling down the measurement from a smaller metric unit to a larger imperial unit, enabling precise and standardized measurements across different systems of measurement.
