These are not units but constant values. And for constants, you have to memorise them for sure as these are used in long calculations.
Also, for constants like speed of light, precision values are avoided and we used rounded values. So instead of using 299792458m/s, you can use 300000000m/s.
And for units, you gotta learn them all. Because you couldn't convert units and values without knowing their relations.
So if you didn't get any of that above, yes, you have to learn them all.
