The use of "ISO" numbers in cameras is a metaphor.

It means: "if you set this number, you can get results similar to those you would get from a film with that ISO number".

There is an ISO standard, but it refers only to the JPG output at the base setting (which is 100 on most cameras). It doesn't apply to raw files.

Wow, that's surprising.  Lots of interesting tidbits here, glad I asked.  Once again, thanks to all who chimed in.
