To find the value in centimeter that corresponds to a value in inches, multiply the value in centimeters by 0.393701 (the conversion factor). Here is the Conversion formula
Value in inches = value in centimeters × 0.393701
Let's say that you have 2.54 centimeters and you want to convert it to inches. By using the conversion formula provided above, you get:
Value in inch = 2.54 × 0.393701 = 1 inch
This conversion formula works because one inch is equal to 2.54 centimeters.
To convert a different value in centimeters, simply replace the value in the formula above with the new value.
What is the Relationship Between Centimeters and Inches
The Exact Relationship is Defined as follows:
1 inch = 2.54 centimeters

Definition of Centimeter
A centimeter (cm) is a metric unit of length equal to one hundredth (1/100) of a meter. This practical unit is widely used in everyday measurements, particularly for small objects and body measurements. One centimeter is approximately the width of an average adult's fingernail. In conversion terms, one centimeter equals 0.3937 inches exactly. Centimeters are commonly used in clothing sizes, furniture dimensions, rainfall measurements, and medical examinations. This unit is particularly useful in education, as it provides an easily understandable scale for teaching measurement concepts to students. In technical applications, centimeters are often used in engineering drawings, crafting, and precision woodworking.
Definition of Inch
An inch (in) is a fundamental unit of length in both the United States customary system and the British imperial system of measurement. Precisely defined as exactly 25.4 millimeters since 1959, the inch has a rich history dating back to ancient measurements based on the human body. One inch was traditionally represented by three barleycorns placed end to end. In modern usage, inches are predominantly used in the United States, Canada, and the United Kingdom for various applications including:
- Screen and display sizes (televisions, monitors, smartphones)
- Construction materials and hardware
- Plumbing fixtures and pipe diameters
- Tire dimensions
- Paper sizes (such as 8.5 × 11 inches)
