New wheels can fit on my bike?
I'am a bit confused. My actual wellset has an Erto of 622x15C and the other wheelset has an erto of 630.
Are them compatibles or i can't mount the second wheelset?

ETRTO is rim/tire bead seat diameter, data..
I expect that you can subtract 622 from 630 then divide that by half..
that is the radius difference between the 2.. your brake pad must reach the rim in both cases..

I was being a smart *** since I could have answered no with equal accuracy.
The BRAKE pads must reach in either case. For the 630 to fit, the pads must have enough room to move a nominal 4mm away from the axle.
Your brakes may or may not have enough adjustment.
The question I ask is WHY? You don't have nearly the selection of tires in 27" as you do with 622.
IF these are old (most are) rims, are they steel? Steel rims have POOR braking compared to aluminum.
Do they have a hook bead? Many old ones don't and limit the pressure they can take before the tire blows off.
There are too many inexpensive 700c wheels out there to want to go to the trouble of adjusting brakes (if possible) etc. for a larger, somewhat obsolete wheel size.

It appears our friend's problem is he got new 700c wheels, but his bike is designed for 27" wheels.
Swapping them back and forth would definitely be a problem.
Modifying his bike to be 700c for the future would be possible with the right brakes.

They have a different bead set diameter by 8mm. 622 is commonly called 700c, 630 is commonly called 27", at least in the USA. You can often use them in the same frame, but you will need to move your brake pads 4mm, which may or may not be accommodated by your brakes. They use different tires.

As posted above, to go from 700c rims (ISO 622) to 27" (ISO 630) your brake pads must move up 4 mm. To go the other way, they must move down 4 mm. Not all brakes can be adjusted that far but most can. Try it first.
Also, 622 and 630 tires are not compatible or interchangeable at all.
BTW, "ETRTO" specifications are now known as "ISO" specifications as ISO has taken over defining these standards.
