PVC gauge is the thickness of the PVC material: 1 gauge = 1/100 mil = 1/100,000 inch = 25.4/100000 millimetre = 0.254 micrometre
19 gauge steel is 1.11 mm thick and 20 gauge is .953 mm thick.

18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.
In Imperial standard (swg), 16 g is 0.064" (1.63mm) thick.

The value "80" in k80 is relatred to the hardness. The gauge related to the weight for a givens surface of material. For example my inflatable kayak is made of k80 28 gauge pvc.
16 gauge
17 gauge = 1.422 mm
18 gauge steel is typically 0.0478 inches thick.
I believe that 30 guage is thicker than 23 guage. If you shop around the higher guage PVC is always on the more expensive items such as water trampolines or white water kayaks/boats.
18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.
Probably 25 gauge, which is .556 mm thick. However, 26 gauge is close too, it is .478 mm thick.
