Understanding the Basics of Centimeters and Inches
What Is a Centimeter?
A centimeter (cm) is a metric unit of length that equals one-hundredth of a meter. It is widely used around the world for measuring small to medium lengths, such as the height of a person, the dimensions of a piece of furniture, or the size of objects in scientific contexts. The metric system, which includes centimeters, is based on decimal units, making conversions straightforward within the system.
What Is an Inch?
An inch (in) is an imperial and U.S. customary unit of length. It is commonly used in the United States, the United Kingdom, and other countries that prefer imperial measurements. Inches are often used to measure things like screen sizes, fabric lengths, or the dimensions of small objects. An inch is defined as exactly 2.54 centimeters, a standard that was internationally agreed upon in 1959.
