Dyne

Dynes redirects here. For the president of the University of California system, see Robert C. Dynes.

In physics, the dyne (symbol "dyn") is a unit of force specified in the centimetre-gram-second (CGS) system of units, a predecessor of the modern SI. One dyne is equal to exactly 10 micronewtons. Further, the dyne can be defined as "the force required to accelerate a mass of one gram at a rate of one centimetre per second squared".

Dynes per centimetre is the measurement usually associated with measuring surface tension. For example, the surface tension of distilled water is 72 dyn/cm at 25 °C (77 °F).

F. f. Greek δυναμις (dynamis) power, force.
