1001 Astonishing Facts about Dyne in CGS

Origins and Evolution

The dyne, a unit of force in the centimetre-gram-second (CGS) system, traces its roots back to the 19th century. In 1873, James Clerk Maxwell proposed a system of absolute units, including the dyne, as part of his treatise on electricity and magnetism. The dyne was officially adopted by the International Committee for Weights and Measures (CIPM) in 1881 as the unit of force in the CGS system.

Definition and Significance

The dyne is defined as the force required to accelerate a mass of one gram by one centimeter per second squared. It is expressed mathematically as:

1 dyne = 1 g cm/s²

The dyne plays a fundamental role in the CGS system, serving as a cornerstone for quantifying forces and their effects. It finds widespread application in various fields, including physics, engineering, and chemistry.
