Is 1/2 inch Baltic Birch a full 1/2 inch thick?

No!!! You can easily measure it with a rule.

Measure once cut twice and it's still to short.

Generally “real” (imported European/Russian) Baltic birch is made to metric sizes. 12mm is often sold as 1/2”, but would be about .03 undersized. I believe Appleply is available in inch sizes. I have bought strips sold for drawer sides that did measure a true 1/2”. Best idea is to measure your actual stock.

From my source, Rockler, Baltic birch plywood is in fact the stated thickness, according to my calipers.

I measured a piece I have cut for drawer stock. It measures 31/64ths on my calipers. That's pretty close to 1/2 inch in my book...12.35mm... .4860 inches.

When I build a drawer and cut a 1/4 inch rabbit, it splits the center ply of the work piece.

I guess it's where you buy it.
I have some that measures right at 1/2" and some that are a full 3/4". And, then there are a few sheets that are a bit less. Probably got them at different suppliers. Can't remember.

If it is listed in the stack as 1/2" and it is 3'4", it has been placed in the wrong stack. Just one of the reasons I always have a tape measure in a vest or jacket pocket.

Fortunate for me, 99.999% of my projects don't call for anything as high quality as Baltic birch, along with the extra expense. AND, doesn't need to be dead on at 1/2", just close. Actually I could even use 1/4" or 3/4" - but using 1/4" would mean making a lot more pieces to get the right thickness, and the 3/4" would give thicker projects with the look thrown off. And, even 3/8" would work, but again, the look would be off in the end. So, 1/2", or close, it is.

I buy mine from a hardwood dealer in Houston. They have all sizes from 1/8th up to 3/4. I don't think I have ever looked for anything thicker. But I have bought some 3/8th inch, and still have a few scraps left from a previous project.

That's my story and I'm stickin' to it!

I buy from several different places especially if they have a good sale going on. I had one shipment of 1/2" panels that were two different sizes, 0.025 difference in size and you could look at the panels and tell which ones were which buy a slight color difference in the materials.

It all depends on where it is manufactured, what company manufactured it, where you buy it and in some instances how and where it was stored.

I think the most important thing here is that it is best to measure each panel before use so you can adjust measurements of the project if needed so you don't have one of those "why doesn't this fit' moments when you are almost finished with the project.
