# All You Need to Know about Inches to Cm Conversion

Knowing how to change inches to cm is a very important skill, especially when working with international standards or communicating with people who use different measuring systems.

Whether it’s purchasing goods from overseas, calculating the dimensions for a design project, or performing scientific tasks, learning how to convert inches to cm will help you present accurate and understandable data.

Find out in this article how to quickly and accurately convert values from one measuring system to another using simple math formulas and tools.

## Inches vs Centimeters. General Description

The inch is widely known in the USA and some other countries of the world that have abandoned the metric measuring system. 1 inch is equivalent to 25.4 millimeters or 2.54 centimeters. The centimeter (cm) is another length unit used throughout the world. It is included in the list of the most common SI metric units and is equal to one hundredth of a meter.

The inch dates back to ancient times when the Romans used the finger as a measurement unit. During the Middle Ages, the British inch was formalized and adopted as a standard measure. It was defined as the width of the first joint of the thumb in men.

The centimeter, in turn, appeared much later, in the 18th century, as a result of the metric revolution, which sought to standardize and simplify all measurements. It is based on the decimal numeral system and is usually defined as 1/100 of a meter.

## Application Areas

Inches help measure the object’s size and length. They are very important in construction and architecture, where precision and compliance with standards play a key role. For example, an inch tape serves as a basis for measuring the width of doorways, windows, or other building elements. The inch system is also used in the automotive and aviation industries.

Centimeters are usually used to determine the length of small objects such as pens, pencils, rulers, pieces of paper, etc. But in fact, the application areas of this metric are very diverse. These are:

• Medicine (measuring organ sizes and body length);
• Construction and engineering (measuring sizes and distances between various objects);
• Topography and cartography (measuring distances on maps, drawings, and plans), etc.

Therefore, inches and cm are very important measuring units that have found application in various areas of human activity.

## Convert Inches to Cm

Transforming inches to centimeters interests many people because different countries use different units for measuring length. The in to cm conversion can be helpful when purchasing products from abroad, taking everyday measurements, studying foreign manuals, etc.

Making conversion yourself is not difficult at all. Just multiply the number of in by 2.54 since there are 2.54 centimeters in 1 inch. Thus, the formula for changing inch to cm will look like this:

centimeters = inches * 2.54
