The dyne (symbol dyn, from Ancient Greek: ?, romanized: dynamis, lit. 'power, force') is a derived unit of force specified in the centimetre-gram-second (CGS) system of units, a predecessor of the modern SI.
The name dyne was first proposed as a CGS unit of force in 1873 by a Committee of the British Association for the Advancement of Science.
The dyne is defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared". An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram".
