Wheel Size Specification?

This is really O/T as I want to use a bicycle wheel for a one off project
with no cycling relevance.
Can someone easily tell me when referring to a 26 inch wheel for example, is
this the diameter including the tyre or is it the diameter of the wheel rim
or maybe even something else?
Thanks for any replies.

Something Else. As always, Sheldon has the answer:

Theoretically it is the diameter including the tire. But those
numbers/names were attached when tire size preferences were far different
than they are now, so they will be far off now. Wheel rim size is
considerably less than the name would suggest. For example, a "700c" rim
measures 622mm

Wheels are male (after all, you buy rubber tubes to put on
them) and there's always a bit of exaggeration about size.
