The rate of para-ortho conversion in solid deuterium (D_2) is calculated taking two types of interactions, i.e., the magnetic dipole-dipole interaction between D_2 molecules and the coupling between the nuclear quadrupole moments of one D_2 molecule and the total quadrupole moment of the other molecule. It is found that both interactions make about the same contributions to the para-ortho conversion if only the interactions among para molecules are taken into account. However, the ortho molecules with I = 2 also interact magnetically with para molecules and convert them into ortho molecules. The calculated conversion rate due to the para-para interactions is found to be 0.01% per hour times c^2, where c is the para concentration, while that due to the para-ortho interactions to be 0.01% per hour times c(1-c), so that the c^2 termes eventually cancel each other, leaving a total conversion rate which is proportional to c.
