Go to the sticky called Sheldon Brown shortcuts and scroll down to "Tire sizing" and click on it. Everything you ever wanted to know, and then some.
Here's the link just in case: https://sheldonbrown.com/tire-sizing.html

Tire sizes sometimes refer to the outside of the tire, if you think about it, this is an uncertain way to measure, as the critical measurement is the diameter of the rim seat. If it don't fit there, the rest don't matter. The important measurement you're looking for is the 622, this is the diameter of the rim bead seat. It's the rim seat measurement of 700c tires.
"how can a 28x1 1/2 fit on a 25 rim?"Simple, the outside diameter is approximately 28" but the bead will measure 622mm within a fairly tight tolerance.

Normally rims will be marked somewhere with their size (622 for a 700C rim). 700C rims are roughly 25" in diameter. 700C tires are going to be 27" or more in diameter depending on the tire size.

Look, just replace the tire with the same size that you had on the bike before. If your old tire says 700c (which DOESN'T mean 700 cm, btw), then get a 700c tire to replace it with. If you had 27" x 1-1/4" tires on there, get 27" tires. The diameter is the most important measurement, you can vary the width within a reasonable range. Any bike shop will make sure you get the right size if you show them the old tire or bring in the wheel or bike.

Read through the Sheldon Brown article again. Really read through it. Study the subject in all its aspects.
Yes, bicycle tire sizing is confusing, mostly because the markings on the side of the tire often have no relationship any real physical measurement of the tire, tube, or rim. If you don't understand that, try politics- that's another subject where what's said doesn't have anything to do with reality.

+1 Look at the markings on your current tire. Take it to the bike shop of your choice. They will sell you exactly what you need.

The 700 is a standard wheel diameter including a tire larger (35mm) than most of us will ride. The "C" is the rim's cross-sectional configuration. A "B" rim is wider than a "C".

A typical current 700 road wheel including the tire is actually smaller in diameter than a 27 inch wheel with tire.

You're confusing terms -- 700c, 27", 29", 26", etc., is TIRE size, not rim/wheel size. That means outside diameter of the tire. OF COURSE the rim will be smaller -- it has to fit inside the tire.
Tires are ALL marked with size info on the sidewall -- replace with the same size, and it's monkey-proof.
Don't make it more complicated than it is.

While I buy a lot of stuff on line, it is best suited for buyers who know exactly what they want. For someone not totally sure, it is cheaper to go 10 miles and buy the right stuff in person. Trying to return on line mistakes is painful.
