How much bigger is a 700 wheel than a 26 inch?

Reason I ask is that I'm looking at this bike with 700 wheels and was wondering if an Old Man Mountain Red Rock rear rack (ha! the alliteration!) will fit on it. I'm afraid of clearance issues. The bike is a Trek 7.3 FX, size 15".

For the record. Is it 700c or 700cc? The bike comes with 700 x 32c tires. What do the numbers and letters mean? Did a google search and still don't get it because there's conflicting info!

700 rim = 622mm diameter 26" rim = 559 mm diameter; 700 x 32c tire approximate (depending on pressure, fabric, yadda yadda...) to 64+622 = 686 mm diameter about the same, again approximately, as 26 x 2.5" tire.

I don't know what the letter means but it's c not cc

I have that rack on a Cross Check with 700x28 tires. Fits just fine with plenty of clearance.

As always, Sheldon has the answer. The letter originally stood for the tire width.
