If I have ChunkX and ChunkZ, how do I get their world coords?
Can I multiply them by 16 to get the start of the chunk? And add 16 to get the end of the chunk?

Multiplying by 16 should work just fine.

Assuming chunk 0,0 is from 0,0 to 15,15

Then chunk 1,0 would be from 16,0 to 31,15

And chunk n,m would be at n*16,m*16 to n*16+15,m*16+15

So actually you multiply by 16 to get the begin and add 15 to the begin to get the last one.
