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.
Facts about Millimeter
Basic facts: A millimeter [American spelling] or millimetre [international spelling – symbol: mm] is a unit of length in the SI (International System of Units). The millimeter is equivalent to one-thousandth of a meter and it is defined as the distance traveled by light in 1/299 792 458 000 of a second.
History: The prefix “milli” is one of many metric prefixes. It shows the base unit’s one-thousandth, in this instance, the meter. The current definition is based on the distance traveled by the speed of light in a given amount of time, however, the definition of the meter has changed over time. The relationship between the meter and the millimeter is continuous. Before this definition, the meter was based on the length of a prototype meter bar. The meter has been re-defined based on the changes made to the definition of a second, in 2019.
Use: The millimeters are used to exactly measure the length of small or narrow objects. On a metric ruler or stick it is the smallest unit of length.
