Cubic Angstrom

A unit that is a non-SI unit, specifically a CGS unit, of polarizability known informally as polarizability volume. The SI defined units for polarizability are C*m^2/V and can be converted to $Angstr\ddot{o}m$^3 by multiplying the SI value by 4 times pi times the vacuum permittivity and then converting the resulting m^3 to $Angstr\ddot{o}m$^3 through the SI base 10 conversion (multiplying by 10^-30).
