80pt is 28mm using online calculator...28mm is 1.1 inches so I am completely confused, can you help me out?

Confusingly, a "point" has more than one meaning. In typography a point is 1/72 of an inch, but in this context it means the same as a "mil" = 1/1000 of an inch. Hence 100 points = 1/10 of an inch, and 80 points is 0.08 inch, which is slightly less than 1/12 of an inch. In metric terms 80 points is 2 millimeters. (Here's the math: 1 inch is by definition exactly 25.4 millimeters and 0.08 x 25.4= 2.032 mm.)

Are these good t make journal cover and punch holes in for the spring?

They'll make a thick one-- they're nice and solid but you'll need a pretty hefty punch for it, so if your punch can't handle a good chunk of paper at a time maybe choose a lighter weight?

How difficult is it to cut these? With scissors or exacto knife? Or small tooth saw? Thanks

Not bad with a good utility knife. Needs more than one pass but a lot easier than 100pt chipboard. I have a Carl cutter and it cuts it with a couple passes whereas 100pt takes me like 10 passes with a good utility knife.

Is it 2.2mm or 2.2cm, it is confusing. How does this translate to Pts.? Thank you

mm. The higher the pt #, the thicker and harder the chipboard is. A cereal box is also chipboard and would be like 20pt I think and it’s pretty thin. 100 pt chipboard is about 3mm and is pretty sturdy stuff
