Pvc pipe sizes referenced in australia and new zealand are mostly in nominal diameter values the reference does not necessarily match up exactly to the outside or inside diameter.
Pvc pipe diameter sizes.
Pvc pipe sizes are different than the size the pipe is called.
So any increase in wall thickness the inside diameter id of the pipe decrease.
As pvc pipe increases in diameter the walls must also be thicker.
Pvc pipe under 14 does not match up exactly with its nominal size see nominal pipe size and o d.
To understand this concept you have to learn the way pipes are manufactured.

The dimensions are listed in inches unless otherwise noted.
However for the pipe sizes nps 14 and above outside diameter is the same as nps.

Manufacturing of nps dn 6 to nps 12 dn 300 pipe is based on fixed outside diameter od.
It does not describe pvc tube or tubing.
This pvc pipe size chart is accurate for all pvc pipe manufacturers as the nominal size is used across the industry.
Depending on the structure of the pvc pipe the internal dimensions can vary for example between solid wall pvc pipes and a sandwich constructed pvc pipes.
Solvent cemented fittings are commercially available to connect pipes based on inches to those based on millimeters.
The od for 1 2 pvc pipe is 0 840 and the od for 3 pvc pipe is 3 500.
For example a 1 inch pvc pipe is actually 1 315 inches in outside diameter and 1 029 inches in inside diameter.
Formufit internal fit products such as internal dome caps adjustable elbows internal couplings and other products that fit inside of the pvc pipe will not work with sch 80 pvc due to the smaller internal diameter.
Fittings follow this same pattern a 1 fitting has a 1 315 inch opening to accept a 1 inch pipe which actually measures 1 315 inches in diameter.
If the walls were too thin the pipe would lack structural integrity.
Outer diameter inside diameter and wall diameter as in wall thickness.
Pvc pipe can come in sizes ranging from 1 8 to 24 and larger.
