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

dyn = 1 g·cm/s² = 10−5 kg·m/s² = 10
µN
The
dyne per centimetre is the unit usually associated with measuring
surface tension. For example, the surface tension of distilled
water is 72 dyn/cm at 25°C (77°F).
