Answer 1

Answer:

The centimetre–gram–second system of units (abbreviated CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.

1 dyn = 1 g·cm/s2 = 10−5 kg·m/s2 = 10−5 N. The dyne per centimeter is the unit traditionally used to measure surface tension.

Dyne.
