In the course of detailed studies of the long-term variations of particular Be stars, we have practically verified that the non-linear transformations, needed for a reliable transformation between a standard and an instrumental photometric system can also be successfully used to the transformations between two particular standard photometric systems. To demonstrate the importance and power of non-linear transformations and to provide pieces of information useful for a broader astronomical community, we summarize the transformation formulæalready published (but hidden from the general community in papers dealing with particular Be stars) and present several other useful transformations derived by us. All transformation formulæpresented here are transformations from various photometric systems to Johnson's UBV system. However, the general procedures applied here would allow construction of similar transformations between other photometric systems, too.
