Facts about Inch

Basic facts: An inch is a unit of length in the United States customary and British imperial systems of measurement [symbol: in]. It is equivalent to 1/36 yard or 1/12 of a foot, meaning there are 36 inches in a yard and 12 inches in a foot. In 1959, an inch was defined to be equal to exactly 25.4 millimeters.

History: The word “inch” is derived from the Roman uncia “twelfth”, the term “inch” is also sometimes used to translate similar units in other measurement systems, usually viewed as deriving from the width of the human thumb, where the length was obtained from averaging the width of 3 thumbs: a small, a medium, and a large one.

In the past, there have been a number of various standards for the inch with the present definition being based on the international yard. One of the earlier definitions of the inch was based on barleycorns [where an inch was equivalent to the length of 3 grains of dry, round barley placed end-to-end].

Use: The inch is mainly used in the United States, the United Kingdom, and Canada. It is also sometimes used in Japan and in other countries as well, in relation to electronic parts, such as the size of display screens.

Facts about Centimeter

Basic facts: A centimeter [symbol: cm] is a unit of length in the SI [International System of Units], centimeter [American spelling], or a centimetre [international spelling]. It is represented as 1/100 meters.  A centimeter is around the width of the fingernail of an average adult person.

History: A centimeter is based on the SI unit meter, it is equal to one-hundredth of a meter as the prefix “centi” indicates.  Based on a decimal system, metric prefixes range from factors of 10-18 to 1018, with the base [in this case the meter] having a factor of 1 and no prefix. In the now deprecated centimetre–gram–second [CGS] system of units, the centimeter was the base unit of length.

Use: Like the meter, the centimeter, is used in all kinds of applications worldwide [in countries that have experienced metrication] in the cases where a smaller denomination of the meter is needed. Outside of countries like the United States height is commonly measured in centimeters. In addition to its use in the measurement of length, centimeters are used to make conversions from map scale to real-world scale [kilometers], also to report the level of rainfall as measured by a rain gauge.
