confused!!!!! how many gallons?

[humerjeep]

Hello,

I am totally confused, I thought I had a 20 gallon tank 36"x12"x12". I have just gone into a thread which was requesting suggestions of stocking a 20 gallon tank 24"x12"x12, if the later size is the case (jumping for joy) as this means I have more gallons to play with. Can some one enlighten me, Thanks

hi humer,

unfortunatly your tank is a 20 gallon (us) tank, the smaller one was a 15 gallon tank.

http://www.animal-world.com/encyclo/information/calculate.htm, this page is a simple tank size calculator. hope your new tank goes well.

20longs are only 30inches long, 12 wide and 12 tall.

I'm thinking your 36long tank may be a 30...not sure though.

Your tank is a 27 gallon.

It's ~20 gallons.

36"x12"x12
36*12*12= 5184
5184/231 = 22.4415584415584

22.4 gallons, but those are outside measurements, so it's really ~20 gallons.

My 20long is 12 deep, 12 high and 30long.............

a 36long, 12deep and 12high has to be larger than a 20..... :huh:

The little calculation done by Roan is correct.
A "20G" with inside measurements of 30x12x12 only holds 18.7 Gallons of water.
You can do these calculations on a lot of tanks and will find that many are off - the "20G" is more a product name than the actual water volume.

Here is a calculator. http://boonedocks.net/fishtank/ftweb.php However everybody did you calculate how thick the wall is?

 

[RTR]

Tanks in the USA are sized in nominal volumes by the exterior measurements. The actual volume is always less than the nominal, sometimes significantly so. For laughs, calculate the volume of a "55" and then measure its actual volume.

The figures Roan Art and Hannys_Papa gave are correct.

 

[joephys]

almost every tank name isn't a true measure of its volume.

Use the calculation that Roan used, or

L x W x H x .0043 = gallons (demensions in inches)

L x W x H x 7.5 =gallons (demensions in feet)
