Landau-Lifshitz books use natural units, but in complex cases they provide dimensional formulas. I have such a case, natural units lie on the proportionality coefficient, so I want to get formulas in dimensional units. This will be useful for you too, you will get rid of errors of natural units. The proportionality coefficient in physical formulas is not predictable, so the count in natural units can lie, it does not take into account, for example, the coefficient of the frequency $2*\pi$ and many other proportionality coefficients.
