Inch to cm conversion: inches to centimeters calculator (2024)

Converting from Inches to Centimeters

To convert inches to cm you need to multiply the value in mm by 2.54 as there are this many centimeters in an inch.

For example, suppose you have a length of 100 inches and you want to convert it to centimeters: multiply 100 by 2.54 which gives you 254cm.

To make the conversion easier, you can use the inches to centimeters conversion calculator provided on this page. This tool will calculate the value for you and you can also enter the inch value in fractional form if required. It is important to note that when converting between inches and centimeters, it is always a good idea to round the result to the desired level of precision, depending on the context of the measurement.

Why convert from Inches to Centimeters?

Converting centimeters to inches is a common task in engineering, manufacturing and construction. Inches are imperial measurements that are normally used in the United States and United Kingdom. Centimeters are a unit of the metric system used worldwide. It is often necessary to convert inches to centimeters when following instructions of specifications in a unit unfamiliar to you.

Centimeters are used where high precision is required such as machining and fabrication. The smaller unit the simpler it is to allow for finer measurements. The metric system offers a logical system of measurement as converting between other metric units are simple and they are based on factors of 10.

About Centimeters

The Centimeter is a unit in the metric system, which is used everywhere around the world apart from the United States and Burma.

Centimeters are smaller than inches. There are 2.54 centimeters in an inch. Centimeters are often used for smaller measurements in science, engineering and construction. They are also used in situations like measuring the length of objects or clothing.

The big advantage of using centimeters rather than imperial units is that they are based on powers of ten.

What are inches?

Inches are commonly used in the United States and the United Kingdom. An inch is defined as one twelth (1/12th) of a foot and used to measure small distances like the length of a pencil or the width of a book.

Inches are often used in construction, carpentry and engineering. They are also often found in the fashion industry for determining clothing sizes and are used to specify screen sizes for TVs and computer monitors.

To convert inches to other units you need to know the appropriate conversion factor. For example, to convert inches to centimeters you need to multiply the inch value by 2.54. To convert inches to millimeters the inch measurement is multiplied by 25.4.

Inches are used mainly in the United States but it is common to find people using inches in the United Kingdom especially for body measurements, trades and fashion. Inches are a standard worldwide in electronics and semiconductors.

Which countries use inches?

The United States is the most notable country that uses inches but a large number of people still use them in the United Kingdom as well. In the US, inches are the standard in construction and engineering. Inches are also common in determining a person's height or the size of television screens.

Although the UK has officially adopted the metric system, inches are still found in certain area particularly in construction. This is due to the historical influence of the imperial system. In the UK inches are also used for body height and objects that were traditionally measured this way such as vinyl records.

Which countries use centimeters?

A majority of countries worldwide have adopted the metric system and as such use centimeters.

In these countries millimeters are the preferred unit for measuring dimensions of building materials, such as pipes, beams, and panels. Centimeters are found in manufacturing, machinery and tools. Centimeters are also used in medicine and are used in the fashion and textile industry.
