Convert inches to cm
Definition: An inch (symbol: in) is a unit of length in the imperial and in the US measurement system. One inch corresponded 1959 exactly 25.4 millimeters. There are 12 inches in one foot and 36 inches in a yard.
History / Origin: The term “customs” is derived from the Latin unit “uncia”, which corresponds to a “twelfth” of a Roman foot.
There have been a number of different customs standards in the past, with the current definition based on the international shipyard. One of the customs’ earliest definitions was based on barley grains, one inch of which corresponded to three grains of dry, round barley arranged throughout. It is also believed that another version of the inch was derived from the width of a human thumb, the length being obtained by averaging the width of three thumbs: a small, a medium, and a large thumb.
Current use: Customs are mainly used in the US, Canada and the United Kingdom. It is also sometimes used in Japan (as well as other countries) in terms of electronic parts such as the size of screens.
Definition: One 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 meter.
Course / Origin: One centimeter is based on the SI unit meters and corresponds, as the prefix “Centi” indicates, 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 counter) having no prefix and a factor of one. Learn some of the most commonly used metric prefixes, such as z, mega, giga, tera, centi, milli, micro, and nano units, which can be useful for fast navigation in metric units.
Current Usage: The centimeter, like the counter, is used in all types of applications worldwide (in countries where a metric has been performed) when a smaller denomination of the meter is required. The height is usually measured in centimeters outside countries such as the United States.
