What is a Centimeter (CM)?
A centimetre, abbreviated as “cm,” is a unit of length in the metric system. It is commonly used in most countries around the world for measuring shorter distances. One centimetre is equal to one one-hundredth (1/100) of a meter, making it a convenient unit for measuring everyday objects like the length of a book or the width of a piece of paper.
History of Centimeter (CM)
The centimeter has a long history dating back to the 18th century when the metric system was first introduced in France. Initially, it was defined as one ten-millionth of the distance from the equator to the North Pole, passing through Paris. However, this definition has evolved, and the centimeter is now based on the length of a specific metal rod kept at the International Bureau of Weights and Measures in France.
What is Inch (IN)?
An inch, symbolized as “in” or “inches,” is a unit of length commonly used in the United States, the United Kingdom, and a few other countries that have not adopted the metric system. One inch is equivalent to 2.54 centimeters. It is frequently used to measure the height of people, screen and display sizes, and various other items, particularly in the United States.
History of Inch (IN)
The inch has a fascinating history dating back to ancient times. Different cultures and regions defined the inch in various ways, often based on the size of a thumb or the width of a human finger. The modern definition of the inch, as 2.54 centimeters, was established through international agreement and standardization.
Centimeters to Inches Formula
To convert centimeters to inches, you can use the following formula:
Inches (in) = Centimeters (cm) ÷ 2.54
How to Convert Centimeters to Inches
