18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.
GAUGE , is one inch thick of steel or metal. So, take this one inch thick of steel sheet and cut it into 12 equal thickness sheets , you get a 12 gauge steel sheet. Similarly, take this one inch thick of steel sheet and cut it into 14 equal thickness sheets , you get a 14 gauge steel sheet. and so on . So, a 12 gauge steel sheet is thicker than 14 gauge , 14 is thicker than 16 , 16 is thicker than 18 and so on. Wrong!!! See my discussion on this...
14 gauge steel is thicker than 16 gauge steel: 0.0781 inches vs. 0.0625 inches.
Thicker.
The thickness of 24 gauge steel is 0.0250 inches or 0.635 mm (USG).
4mm sheet metal falls 24 gauge and 25 gauge. 24 gauge sheet metal is 3.175mm (0.125") thick, and 25 gauge sheet metal is 6.35 (0.25") mm thick.

The difference between 18 gauge and 22 gauge stainless steel is the thickness. The 18 gauge is 0.050" thick, and the 22 gauge is 0.031" thick. A link is provided below to an article with a list of the conversions. You'll note that the cited thickness for the gauges of stainless do not apply to galvanized steel, aluminum, zinc, brass or other metals.
