Understanding the Fundamentals: Centimeters and Inches
Before diving into the conversion, let's refresh our understanding of centimeters and inches. Both are units of length, but they belong to different measurement systems:
Centimeters (cm): Part of the metric system, widely used internationally. One centimeter is roughly the width of your pinky fingernail.
