I'm trying to join a pipe to a pvc connector, I got one from the hardware store that seemed to match in size perfectly, but when I tried to screw it on, the thread seemed to not match, are there two 'threads' for pvc connectors, here's a picture of the sort of connector I'm using. Is it a metric / imperial thing?
It sounds like you're using a crappy copper pipe cutter. To cut PVC, you want one of these instead:
I've used mine to cut thousands of PVC pipes and it does the job quickly and easily. You can probably find one for less than $10 and it will serve you well for life.
Can you make this adapter work?
This one converts a male 1/2 inch thread to an M22 size. You can see it for sale at this web site.

The threads at the union nut are not standardized, each manufacturer is likely to have their own thread. In fact, I suspect they deliberately use proprietary threads to force you back to their brand.
It is not at all uncommon for you to have to cut back and couple in an entirely new union.
