The units all work together, so if you use some quantities in SI units, other quantities that you calculate from them will also be in SI units. Imagine if scientists in the US had one way of measuring mass, scientists in Europe had a different method, and scientists in Asia had a third method. At a much, much smaller scale, particle physicists working at the atomic scale oftentimes use the electron charge and electron mass as the units of charge and mass; the other units are chosen to make $\hbar$, $k_e$, and $k_B$ all have numerical values of one.
