What is the Full Form of CGS

CGS: Centimetre-Gram-Seconds

CGS stands for centimetre-gram-seconds. The centimetre-gram-seconds (shortened as CGS or cgs) is a typical unit system. It is a version of the metric system, which uses the "centimetre" as the unit of length, the "gram" as the unit of mass, and the "second" as the unit of time. These three fundamental units are the source of all CGS mechanical units. Also, there are several ways the CGS system has been expanded to also include electromagnetism.

CGS Full Form

The MKS system has replaced the CGS system and is based on the metre, kilograms, and second. The MKS system was then expanded and superseded by the SI ("International System of Units"). Although "SI" is the only system of units employed in multiple research and engineering professions, CGS is yet broadly utilised in some of their subfields.

The CGS system was presented as a basis for an absolute unit system based on the three basic units of length, mass, and time.


The CGS system was presented by the German mathematician "Carl Friedrich Gauss" in 1832. Gauss selected the millimetre, milligram, and second units. However, a committee of the British Association for the Advancement of Science suggested in 1873 that the basic units of a centimetre, gram, and second be adopted globally. Since then, all derived electromagnetic units have been expressed using the prefix "C.G.S. unit of...".

The technical use of CGS units had gradually decreased globally since the 1940s when the MKS standard was adopted internationally. Later in the 1960s, the SI standard was also gradually adopted.

In the early 1880s and greatly by the middle of the 20th century, the CGS system was slowly replaced for scientific purposes on a global scale by the MKS system, which later developed into the current SI standard. SI units were then primarily used in engineering disciplines and physics education. Despite this, Gaussian CGS units were frequently employed in "theoretical physics", "relativistic electrodynamics", and "astrophysics".

Nowadays, the SI unit system is the most common international standard metric system and is also the system most widely used around the world.


Many CGS units' sizes ended up being unsuitable in real-world applications. For instance, many commonplace items, such as people, rooms, and houses, are thousands or hundreds of centimetres long. Because of this, the CGS system never took off outside the scientific community.
