What is the difference in gauge and mil when it comes to above ground swimming pool liners?

Gauge and mil are both units of measurement used to describe the thickness of above ground swimming pool liners. However, there is a slight difference between the two.

Gauge is a measure of the thickness of the material in thousandths of an inch. For example, a 20 gauge liner is 0.020 inches thick.

Mil is a measure of the thickness of the material in thousandths of a millimeter. For example, a 20 mil liner is 0.020 millimeters thick.

So, a 20 gauge liner is the same thickness as a 20 mil liner.

When it comes to choosing an above ground swimming pool liner, the thickness is an important factor to consider. The thicker the liner, the more durable it will be. However, thicker liners are also more expensive.

For most above ground pools, a 20 gauge or 20 mil liner is a good choice. These liners are thick enough to be durable, but they are also affordable.

If you are looking for a very durable liner, you can choose a thicker liner, such as a 25 gauge or 25 mil liner. However, these liners are more expensive.

Ultimately, the best thickness for your above ground pool liner depends on your budget and your needs.
