A barad is a dyne per square centimetre ($dyn \cdot cm^{-2}$), and is equal to $0.1 Pa $ ($1 \, micro \, bar$, $0.000014504 \, p.s.i.$). Note that this is precisely the microbar, the confusable bar being related in size to the normal atmospheric pressure, at $100\,dyn \cdot cm^{-2}$. Accordingly barad was not abbreviated, so occurs prefixed as in $cbarad = centibarad$. Despite being the coherent unit for pressure in c.g.s., barad was probably much less common than the non-coherent bar. Barad is sometimes called $barye$, a name also used for $bar$.
