Explanation:
This conversion process relies on two key relationships:
- 1 inch = 2.54 cm: This is the fundamental conversion factor between centimeters and inches.
- 12 inches = 1 foot: This is used to convert the inches into feet.
The first step is converting centimeters to inches, which is achieved by dividing by 2.54. This gives us 67.72 inches. The second step is converting the inches into feet by dividing the total number of inches by 12. Since 67.72 inches is not exactly divisible by 12, we get a decimal number, 5.64, which corresponds to 5 feet 7 inches when considering the decimal part (0.64) as a fraction of 12 inches. To make it simpler, we round the result to the nearest inch.
Understanding this process helps when converting any length from centimeters to feet, especially in countries where the imperial system (feet/inches) is used, such as the United States.
