What you have there is actually a cheat. These are usually calculated with a special cheat search in the emus themselves. What a cheat does, is that it overwrites the RAM. You can not find this address in a hex editor, since you are viewing the ROM there.
You also can not "convert" the Ram address into the Rom address (SNES or PC address for that matter).
It only way to do this is to trace the code on the spot, where the Ram-overwrite steps into the effect. The tracing is actually the first step of Asm modding. Looking at the tracers log, it should be clear where the code is read and where the pointer to that code is. Or in other words, this gives you the rom snes address, which can then be converted into the rom pc address; and that's what the hex editor is displaying.
I've seen this done for Alttp menu items, which you can get by entering cheats (overwriting the ram). The rom addresses for them, as well as the values were completely different.
You will need people with asm/tracing skills to pull this off.
