# Air Tanks

Do you have a question about compressed air tanks for your air compressor?

Are you looking to plumb an extra tank to your air compressor? This page is intended to provide you as much information about compressor air tanks as possible.

A pet and persistent itch of mine is why air tank size is measured in gallons, and compressed air is measured in cubic feet? How do you convert between the two if you wish to?

### Air Tanks Size

How do you convert between gallons and cubic feet? You divide the number of gallons of the tank size by 7.48

(7.48 gallons = 1 cubic foot)

Or, you can multiply gallons by 13.4% (.1337) to get the number of cubic feet in the air tank, as well.

For example, 300 gallons = approximately 40 cubic feet.

If you can answer a question about compressor air tanks please comment as it will help many compressor owners.

Thanks,

Bill
