Inch
Definition: An inch (symbol: in) is a unit of length in the imperial and US customary systems of measurement. An inch was defined to be equivalent to exactly 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard.
History/origin: The term “inch” was derived from the Latin unit “uncia” which equated to “one-twelfth” of a Roman foot.
There have been a number of different standards for the inch in the past, with the current definition being based on the international yard. One of the earliest definitions of the inch was based on barleycorns, where an inch was equal to the length of three grains of dry, round barley placed end-to-end. Another version of the inch is also believed to have been derived from the width of a human thumb, where the length was obtained from averaging the width of three thumbs: a small, a medium, and a large one.
Current use: The inch is mostly used in the United States, Canada, and the United Kingdom. It is also sometimes used in Japan (as well as other countries) in relation to electronic parts, like the size of display screens.
Centimeter
Definition: A centimeter (symbol: cm) is a unit of length in the International System of Units (SI), the current form of the metric system. It is defined as 1/100 meters.
History/origin: A centimeter is based on the SI unit meter, and as the prefix “centi” indicates, is equal to one hundredth of a meter. Metric prefixes range from factors of 10-18 to 1018 based on a decimal system, with the base (in this case the meter) having no prefix and having a factor of 1. Learning some of the more commonly used metric prefixes, such as kilo-, mega-, giga-, tera-, centi-, milli-, micro-, and nano-, can be helpful for quickly navigating metric units.
Current use: The centimeter, like the meter, is used in all sorts of applications worldwide (in countries that have undergone metrication) in instances where a smaller denomination of the meter is required. Height is commonly measured in centimeters outside of countries like the United States.
How to convert inches to centimeters
1 inch is equal to 2.54 centimeters:
1″ = 2.54cm
The distance in centimeters (cm) is equal to the distance in inches (″ or in) times 2.54:
distance(cm) = distance(inch) × 2.54
Example
Convert 20 inches to centimeters:
distance(cm) = 20″ × 2.54 = 50.8cm
How many inches in a centimeter
One centimeter is equal to 0.3937 inches:
1cm = 1cm / 2.54cm/in = 0.3937in
How many centimeters in an inch
One inch is equal to 2.54 centimeters:
1in = 2.54cm/in × 1in = 2.54cm
How to convert 10 inches to centimeters
Multiply 10 inches by 2.54 to get centimeters:
10in = 2.54cm/in × 10in = 25.4cm

What is Meant by the Inch to Centimeter Conversion?
An inch is a customary system used to measure the length or distance. It can be defined as a unit of length of measurement. It is represented using the symbol, ” or in. A centimeter is a metric system used to measure the unit of length. It is abbreviated as “cm” where 1 cm is defined as 1/100 meters.
1 centimeter = 0.01 meter = 10 millimeter = 0.3937 inches.
In order to convert the inches to centimeters, one should follow the below points.
1 inch is equal to 2.54 centimeters.
1” = 2.54 cm
To find the length or distance in cm, multiply the distance in inches with 2.54
Distance (cm) = Distance (inch) x 2.54
It means that to convert inches to centimeters multiply the given figure by 2.54.
Inch Definition
An inch is defined as the measurement unit used in Imperial and the US Customary measurement systems. It is the unit of length. The unit “inch” is mostly used to measure the electronic parts, like TV, mobile phones, laptop display screens. It is represented using the notations in or “.
Centimeter Definition
The unit centimeter is also used to measure the length, and used in the International System of Units, which is the current form of the metric system. It is represented using the notation “cm”. It is mostly used in all sorts of applications and widely used to measure the height of the object.
Inches to Centimeters Calculation
Both the units inches and centimeters are used to measure the length or the height of the object. It is essential to learn the conversion values from one unit to the other unit without changing the relative amount of the given quantity. The relation between inch and centimeter is as follows:
1 inch (1 “) = 2.54 centimeters
Or 1 centimeter = 0.393701 inches
Let us consider an example, 30 inches in cm is converted as follows:
We know that one inch is equal to 2.54 centimeters.
Thus, to convert 30 inches in cm, we have to multiply 30 inches by 2.54.
(i.e.) 30 x 2.54 = 76.2 centimeters.
Hence, 30 inches in cm is equal to 76. 2 cm.
Similarly, we can convert any inches value to the equivalent centimeter value.
Inches to Centimeter Formula
The formula to convert the length or height given in inches into its equivalent centimeter is given by;
The value of 1 inch is approximately equal to 2.54 centimeters.
It means that
1 in = 2.54 cm
To convert inches to the centimeter values, multiply the given inch value by 2.54 cm.
Similarly, the conversion of centimeters to inches can proceed as follows
We know that 1 inch to equivalent to 2.54 cm
Therefore, 1 cm = 1 / 2.54
1 cm = 0.393701 inches.
