Practical Examples of Conversion
Let's look at some practical examples of converting between centimeters and inches:
Example 1: Converting a Length
Suppose you have a piece of wood that is 15 cm long. To convert this to inches:
Inches = 15 cm × 0.393701
Inches = 5.905515
Therefore, 15 cm is approximately 5.91 inches.
Example 2: Converting a Width
If you have a fabric that is 20 cm wide, to convert this to inches:
Inches = 20 cm × 0.393701
Inches = 7.87402
Therefore, 20 cm is approximately 7.87 inches.
Example 3: Converting a Height
For a person who is 175 cm tall, to convert this to inches:
Inches = 175 cm × 0.393701
Inches = 68.897675
Therefore, 175 cm is approximately 68.90 inches.
