What Is Centimeter (CM)

The unit of length of the International System of Units “meter” (metre) originated in France, and in May 1790 a special committee of French scientists recommended that one fortieth of the total length of the Earth’s meridian through Paris be used as the unit of length – the meter. -The metre was approved by the French Parliament in 1791.

In order to make a reference device to characterize the value of the meter, measurements were made from Dunkirk, France to Barcelona, Spain from 1792 to 1799 under the leadership of the French astronomers Jérien Bourg and Mizin. The distance between the two ends of this bar was defined as 1 meter and handed over to the French archives for safekeeping, so it was also called “archival meter”. This is the earliest definition of rice.

Due to the serious deformation of the archival meter, the definition of the “archival meter” was abandoned in 1872, and the unit of length was taken as the original meter made of platinum alloy (90% platinum and 10% iridium).

In 1889, at the First International Congress of Weights and Measures, the metre gauge No. 6, which had been certified by the International Bureau of Weights and Measures, was put into the notch (neutral side) of the ruler. 31 meters in 0 ℃ closest to the length of the archives of a meter) was selected as the international meter, and as the world’s most authoritative length benchmark kept in the basement of the International Bureau of Weights and Measures in Paris, the rest of the ruler as a secondary ruler distributed to participating countries.

In 1927, the Seventh International Congress of Weights and Measures made strict regulations on the definition of meter, in addition to the temperature requirement, it also proposed that the meter must be kept at 1 standard atmosphere, and made specific regulations on its placement method. However, there are many drawbacks to using the metre gauge as an objective standard for meters, such as material deformation;

The measurement accuracy is not high (only up to 0.1 μm). It is difficult to meet the needs of metrology and other precision measurements. In addition, in case the original meter is damaged, there will be no basis for replication, especially the replica is difficult to ensure complete consistency with the original, bringing difficulties to the use of countries.

Therefore, the idea of using natural measurements as a unit reference has always been desired. 1950s, with the development of isotope spectral light sources. The discovery of the very narrow width of the krypton-86 isotope spectral line, coupled with the success of interference technology, people finally found a natural standard that is not easily destroyed, that is, the wavelength of light waves as a natural reference for the unit of length.

The 11th International Congress of Weights and Measures in 1960 changed the definition of the meter as follows: “The length of the meter is equal to 1650763.73 times the wavelength in vacuum of the radiation leaping between the 2p10 and 5d1 energy levels of the krypton-86 atom”. This natural reference, stable performance, no deformation problems, easy to reproduce, and has a very high reproduction accuracy. China also established the krypton-86 isotope length reference in 1963.

After the definition of meter was changed, the international meter progenitor was still kept in the International Bureau of Weights and Measures according to the original regulations. With the progress of science and technology, the determination of time and the speed of light have reached a high degree of accuracy since the 1970s.

As a result, a new definition of meter was adopted at the 17th International Congress of Weights and Measures held in Paris in October 1983: “meter is the length of light traveling in a vacuum during a time interval of 1/299792458 seconds”. Thus, the definition of meter based on the wavelength of spectral lines was replaced by the new definition of meter.

The decimeter (decimeter or dm) is one of the metric units of length, and one decimeter is equivalent to one-tenth of one meter.

0.1 meter (m) = 1 decimeter (dm)

10 centimeters (cm) = 1 decimeter (dm)

100 millimeters (mm) = 1 decimeter (dm)

10 decimetres (dm) = 1 metre (m)

0.1 decimeter (dm) = 1 centimeter (cm)

0.01 decimeter (dm) = 1 millimeter (mm)

What is Inch?

The word “inch” comes from the Old English “ynce”, which is also the Latin “uncia” (meaning “one twelfth”). The word “inch” comes from the Old English “ynce” and the Latin “uncia” (meaning “one-twelfth”), which in Dutch originally meant thumb, and at that time meant that one inch was the length of one thumb. Of course, the length of a human thumb varies. It belongs to the British system of length measurement, is only in the United States and other very few countries are still used, it is defined as 1/36 yards, or 1/12 feet, in the 14th century, King Edward II promulgated the “standard legal inches”. The regulation is: from the middle of the barley spike to select the three largest grains of wheat head to head in a row length is 1 inch. Before the definition of inches is more confusing, different countries have different standards are quite different, until the last century after the adoption of the international code in the 1950s and 1960s, inches to metric units based on the precise definition of 25.4 millimeters, that is, 2.54 centimeters.

In daily life, the size of the display of our electronic products is usually measured by the length of the diagonal line, in “inches” as a unit. Calculate the number of inches of the screen of electronic products is: measure out the screen diagonal how many centimeters, and then the number of diagonal centimeters divided by 2.54, you can know how many inches of the screen.

Common conversions between inches and metric units of length:

1 inch = 2.54 centimeters;

1 inch = 25.4 millimeters;

1 inch = 0.254 decimeters;

1 inch = 0.0254 meters;

1 meter = 39.37 inches;

1 decimeter = 3.937 inches;

1 centimeter = 0.3937 inches;

1 millimeter = 0.03937 inches.
