Stick with the bong for a cleaner, denser smoke.
Well 15mm/1/2inch and 22mm/3/4inch are sort of compatible because you can get couplers, soldered or compression that join them. Once you've done that you would install new pipework to whatever you are fitting in new metric pipe.
sorry your question is too vague. Do you want copper pipes or plastic or GMS ? and what sort of size ? 10mm or 600mm ID. If its domestic type fittings you want you will have to buy metric pipe and metric/imperial adaptors
If you mean domestic copper, 15mm matches 1/2 inch, 28mm matches 1 inch. 22mm is the odd one out, slightly larger than 3/4 inch, but use compression fitting and a 22mm - 3/4 olive.
it may be cheaper and more practical to solder together an imperial and metric fitting then use metric fitting from then on after the join. Its very easy to do.
