Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

I am trying to figure out how to convert square feet into u.s. gallons. Example: 40' L x 30'W x 2"H. What would be the amount of u.s. gallons to fill this area?

You have to convert a cubic, not square measure into gallons.

1 gallon = 231 cu in, so

40' x 30 ' x 144 sq in/sq ft x 2" = 345,600 cu in

x 1 gal/231 cu in = 1496.1 gallon.

Hope you're filling it with something cheap.

Multiply all three figures together to get cubic feet.

As there are 7.4805 gallons in a cubic foot, multiply the cubic feet you get from calculating the above by 7.4805.

That's 4560 inÂ³.

At 231 inÂ³/gallon, 19.74 gallons.

OK below answer has an error

a cubis foot + 12 inches x 12 inches that is a square foot

multiply that x another to get a cubic foot

so a cubic foot is 12 x 12 x 12 = 1728 cubic inches

the below pond was 10 x 12 say 3 feet deep that is 360 square feet

360 x 1728 = 622,080 cubic inches

or multiply 360 square feet x 7.48 galons per square foot = 2,692 gallons

a cubis foot + 12 inches x 12 inches that is a square foot

multiply that x another to get a cubic foot

so a cubic foot is 12 x 12 x 12 = 1728 cubic inches

the below pond was 10 x 12 say 3 feet deep that is 360 square feet

360 x 1728 = 622,080 cubic inches

or multiply 360 square feet x 7.48 galons per square foot = 2,692 gallons
