Understanding the Basics of Conversion

Before diving into the nuts and bolts of converting centimeters to feet, let's establish some basic understanding:

• Centimeter (cm): A unit of length in the metric system equivalent to 1/100th of a meter.
• Feet (ft): A unit in the Imperial system, traditionally used in the USA and UK, where 1 foot equals 12 inches.

Conversion Factors:

To convert centimeters to feet, you'll need to use the following conversion factor:

• 1 inch = 2.54 cm
• 1 foot = 12 inches
• Therefore, 1 foot ≈ 30.48 cm

Now, let's dive into the how-to of converting 138 cm to feet.
