About this tool
The centimeter (cm), one hundredth of a meter, is the metric unit most commonly used for body measurements, clothing, and small objects in nearly every country in the world.
The inch traces back to old measures based on the width of a thumb or three barleycorns, and was standardized in 1959 as exactly 2.54 centimeters. It remains in everyday use in the United States for height, screen sizes and woodworking.
This converter is often used to translate a height, screen size or measurement between the two systems — for example, converting a European clothing or shoe measurement, or checking what a TV's screen size in inches means in centimeters.
