Converting old photometry units

I am interested in converting data between some old astronomical units
like:

candelas per square meter
magnitudes per square arc second
lamberts
foot-lamberts
integrated magnitudes

Could someone recommend a book or article that I could refer to with
some math examples? I have reviewed:
