Diffusive conductance to CO2 is generally about ~1.6x that of H2O because of the higher molecular weight. To convert, multiply conductance by the ratio of diffusion coefficients:
g_c = g_w D_c / D_w
g_w = g_c D_w / D_c
Value with units μmol / (m^2 s Pa) of class units.
This function will soon be moving to the standalone gunit package.
