système international d'unités

The SI is a system of units that was adopted in 1960 as a single practical system of units that could be adopted by all contracting parties to the Metre Convention. Its international abbreviation is SI, which stands for système international d'unités in French.
[History]

Since its application in 1832 to the measurement of the earth's magnetic field, and with the start of the provision of standards by the International Bureau of Weights and Measures in 1889, it has spread widely to science and technology due to its rationality. At the same time, convenient units were created for each application field, and various unit systems were differentiated. However, new units and standards needed to be created in the field of electromagnetism, which became popular in the 19th century.
