What is a Centimeter?

A centimeter (cm) is a unit of length in the metric system, which is the most widely used system of measurement in the world, including Europe, most of Asia, and many other countries. It is based on powers of 10, making it a decimal system, which makes conversions between different units of measurement relatively easy.

What is a Inch?

An inch is a unit of length or distance commonly used in the United States, as well as in a few other countries that have not adopted the metric system. It is part of the imperial and U.S. customary systems of measurement. The abbreviation for an inch is "in" or sometimes double quotes (").
One inch is equivalent to exactly 2.54 centimeters in the metric system. In the imperial and U.S. customary systems, 12 inches make up one foot. So, it is a smaller unit of measurement in those systems, used for shorter distances, such as measuring the length of a book, the height of a person, or the dimensions of smaller objects.

Decimal inches and Fractional inches

Inches can be expressed in two primary ways: as inches in decimal form and as inches in fraction form. Here's an explanation of each:
Inches in Decimal Form: This is the more precise and common way to represent inches in a decimal format. This format is often used in scientific and engineering contexts where precise measurements are important. It's also the format used when converting inches to centimeters, where 1 inch is exactly equal to 2.54 centimeters.
Inches in Fraction Form: In everyday use, especially in carpentry and construction, measurements are often expressed in fraction form. This format is more convenient for many practical applications where precise decimal measurements are not necessary.
