To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 cm. The formula for converting centimeters to inches is given by:

\([ \text{length in inches} = \text{length in cm} \div 2.54 ]\)

Applying this formula to convert 12.8 cm to inches:

\([ 12.8 \ cm \div 2.54 = 5.0393700787 \ inch ]\)

However, for practical purposes, it's often rounded to two decimal places, making it approximately 5.04 inches.

The process of conversion involves dividing the number of centimeters by the value of an inch in centimeters. Since one inch is defined as exactly 2.54 centimeters, this conversion factor is used to change the units from the metric system (centimeters) to the imperial system (inches). This method provides an accurate and standardized way to convert measurements between the two systems, allowing for precise and consistent communication of lengths and distances regardless of which unit system is being used.
