Definition of a Centimeter

A centimeter is a measurement that is represented as a unit of length in the metric system. One centimeter

is equal to one tenth of a meter, and the term centimeter is shortened to "cm." The metric system includes a variety of length units such as feet, gram, kilogram, and so on. The base unit of the CGS (Centimeter-gram-second) system is cm.

History/origin: As the prefix "centi" suggests, a centimeter is based on the SI unit meter and is equal to one-tenth of a meter. Metric prefixes range from factors of 10-18 to 1018 in a decimal system, with the base (in this case, the meter) having no prefix and a factor of 1. Knowing metric prefixes such as kilo-, mega-, giga-, tera-, centi-, milli-, micro-, and nano- will help you explore metric numbers more quickly.

Current use: The centimeter, like the meter, is used in a variety of applications around the world (in countries that have adopted metrication) when a smaller denomination of the meter is necessary. Outside of countries such as the United States, height is generally measured in cm.

Inch Definition

In mathematics, the traditional approach is used to calculate length, weight, capacity, and temperature. It is entirely dependent on the English metric system. The unit of length of measurement in the traditional measurement method is the "inch."

History/origin: The term "inch" was derived from the Latin unit "uncia" which equated to "one-twelfth" of a Roman foot.

The inch has had several distinct definitions over the years, with the current one being based on the international yard. One of the earliest definitions of the inch was based on the length of three grains of dried, spherical barley arranged end-to-end. Another variant of the inch is thought to have been determined from the width of a human thumb, with the length calculated by averaging the width of three thumbs: small, medium, and huge.

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) for electronic parts, like the size of display screens.

 

Relation Between Inch and Cm

To convert cm to inches or inches to cm, the relationship between inch and cm is that one inch is exactly equal to 2.54 cm in the metric system.

1” = 2.54 cm

Therefore,

1 cm = 1/2.54 inches

Therefore, to convert cm to inches, we need to divide the value in centimeters by 2.54.

For a 1 cm length unit, the corresponding length in inches is equal to 1cm = 0.393701 inches

 

How to Convert Centimeters (cm) to Inches (in)

With the help of this length converter, we can easily convert cm to inches like 10 cm to inches, 16 cm to inches, 18 cm to inches, 35 cm to inches, etc. As we know one centimeter is approximately equal to 0.393701 inches, the conversion from the unit centimeters to inches can be performed easily. To convert centimeters to inches, multiply the given centimeter value by 0.393701.

For example, to convert 10 centimeters to inches, multiply 10 centimeters by 0.393701 to get the inches value.

(i.e.,) 10 x 0.393701 = 3.93701 inches.

Hence, 10 centimeters is approximately equal to 3.93701 inches.

Now, consider another example, 30 cm to inches is converted as follows:

As we know 1 cm = 0.393701 inches

Thus, 30 cm to inches can be converted by multiplying 30 by 0.393701 inches.

(i.e., ) 30 cm to inches = 30 ×0.393701 inches

= 11.81103 inches

Hence, 30 cm is approximately equal to 11.811 inches.

Similarly,

• 12 cm in inches: 12 x 0.3937 = 4.7244
• 15 cm in inches: 15 x 0.393701 = 5.90551
• 40 cm in inches: 40 x 0.3937  = 15.748 
• 50 cm in inches: 50 x 0.3937 = 19.685
