dyne

Forceexact by definition

The dyne is the CGS unit of force, the force that accelerates one gram at one centimetre per second squared. That makes it exactly 10⁻⁵ newtons, an exact relation since both systems are decimal. It is now rare except in surface tension work, where dyne per centimetre remains common.
