Gauge is the term that comes to mind, such as 12 gauge (ga.) wire. With plastic bags, one might use mil, such as a 3 mil garbage bag. "Mil" indicates thousandths of an inch.
.001 inch = 1 mil

decimal that is equivalent to 18 = 18.0
16/18 = 8/9 in its lowest terms
The ratio of gauge to mil in plastic thickness is 1 gauge = 0.1 mil. This means that for every 1 gauge increase, the thickness increases by 0.1 mils.
Convert gauge to mil

18 gauge is thinner than 10 gauge.
Gauge and mil refer to the thickness of the liner. To find the thickness when listed by gauge ask for the type of material and check for the converted value ( ie a 10 gauge liner may equate to perhaps a 0.14 inch thickness material , 8 gauge may be 0.12 inches etc ) The mil value usually refers to a millimeter thickness (ie 15 mil should be thicker than a 10 mil ) >KEEP IN MIND THAT THE MIL NUMBER IS NOT IN INCHES , so make sure what the mil value is given in millimeters or inches then you can compare the different thicknesses. If the pool dealer doesnt know the difference you may want to find another dealer
The 1 Mil is equivalent to 0.001 inch. The higher the mil the thicker that product would be. So, 4 mil is thicker than 3 mil.
Gauge is the equivalent of a "mil" which is "thousandths" of an inch.Hence, a 20-gauge pool liner would be 20-mil which is 20 thousandths of an inch or 0.020" = 0.02 inches. A 30-gauge liner would be 30-mils or 0.03 inches....Answermost above ground pools are 20 mil and in ground liners are usually 30 mil
18 gauge is thicker than 20 gauge. 18 gauge is 1.27 mm thick while 20 gauge is .953 mm thick.
