As you probably know, the inch is the unit of length used by people in some countries. It is not as popular as the centimeter, but is used very often. In most countries you can meet the inch, for example, in shops with electronic equipment. A screen size of a TV set or a smartphone is identified by inches.

But, since you are here, you probably don’t know how an inch is defined. The easiest way to explain it is by comparing the **inch to cm** and illustrate the principle of the **inch to cm conversion**.

First of all, you have to know that there exists something called **the inch to cm ratio**. This ratio determines how many centimeters are in the inch. As agreed with the specialists, **1 inch is equal to 2.54 cm**:

**1 inch = 2.54 cm.**

This is the answer to the question asked in the title. We could define the inch using other units of length, but it is the best way to define it by centimeters. The centimeter, as you already know, is the most popular unit of length, because it is the part of the metre.

On the basis of the mentioned **inch to cm ratio** you can convert **inches to cm**.

How to do it? How to **change from inches to cm** manually? You have to remember only one general equation called the **inch to cm equation**. It looks as follows:

**The number of inches * 2.54 = The number in centimeters.**

Using this general **inch to cm equation** you can convert any value identified by **inches to cm**.

Let’s see an example. We will convert **59 inches to cm**. According to the **inch to cm conversion formula** based on the **inch to cm ratio** and the **inch to cm equation**, we have to multiply 59 by 2.54 to get the result in centimeters. It looks as follows:

**59 inches * 2.54 = 149.86 centimeters.**

Done. It is really easy, isn’t it? You only have to know how to multiply the numbers in writing. But, there is one disadvantage of a manual **inch to cm conversion** – speed. It will probably take you a lot of time to convert very high values in** inches to cm**.
