The Basics: Understanding Centimeters and Inches
Centimeters: A Metric Unit of Length
Centimeters belong to the metric system, a widely used system of measurement based on multiples of 10. One centimeter is defined as one-hundredth of a meter, the fundamental unit of length in the metric system. Centimeters are commonly used to measure small lengths, such as the size of objects, the height of people, or the width of rooms.
Inches: An Imperial Unit of Length
Inches, on the other hand, belong to the imperial system of measurement, which is primarily used in the United States and a few other countries. An inch is defined as one-twelfth of a foot, which is the base unit of length in the imperial system. Inches are often used to measure lengths in everyday life, such as the height of a table, the length of a pencil, or the size of a computer screen.
