How many gallons am i ?

Thats a stock 20 US gallon tank. Its not exactly 24"x12"x15", the dimensions should be measured from inside the tank, it comes out not an even measurement. When dealing with fish tanks, we generally round to the nearest 5 gallons, so your tank, though it only contains say 19 gallons, is called a 20 gallon.

Yes I was thinking the same thing "who makes an 18 gallon fish tank?" But that's what my calculations say it is. That calculator on there says my 10 gallon is a 7.394 somthing. That's not right for sure. I don't know about those online calculators. ;D

That calculator is honestly fubar. But your measurement of 7.394 is in imperial, or UK gallons. We use US gallons, and a stock ten is about 10.5 gallons, the site says 8.9 or so.
Volume of a tank:
Length x Width x Height = Volume in cubic inches or centimeters, depending what you used.
To convert cubic inches into US gallons, divide by 231.

I was right on how to calculate the gallons though. ;D:-/
I have to jump in to clarify some issues that you have highlighted with online calculators. Particularly those at http://www.notcatfish.com/reference/calculators.htm
This volume calculator takes in to account the tank being filled to 4cm (1.75 inches) from the top - aquariums are never filled to the brim!
The page also clearly states "Water volume will be also be reduced through displacement by the substrate, filters, fish and furnishings and the thickness of the aqurium walls......The calculator does NOT allow for these variable factors."
The only way to determine the *exact* volume of any aquarium is to measure the water as you fill the aquarium. Even then, there will be displacement caused by the fish and plants and the accuracy of any measurements on the side of buckets must also be considered.
I have checked the values returned by these calculators against actual aquarium volume and found them to be more than acurate enough for any aquaria realted use e.g. medicating an aquarium.
As a point of note, the calculation that it performs is 100% correct.
Finally, as has beeen previously mentioned, US aquariums will rarely contain the actual volume of water that they claim but will hold a volume in close proximity. Similarly my UK, 72x24x24 aquarium would be said to hold 600 litres where as the actual volume is some 5% more.
Thsi illustrates the better method of describing the size of an aquarium is by length, height, depth. That way you get a better appreciation of dimension than with volume.

Hi notcatfish! Its a pleasure to meet you! Are you the 'owner' of notcatfish.com. Nevertheless, I really enjoy your site. It has many good articles and profiles that have been a great help. I followed most of your info especially about setting up and decorating a tank ie. rocks, wood, background, etc. You can see my pics if you click on the www located at the bottom of this post. Keep up the good work and thank you.
Hi,
Yes I am the webmaster of said site.
I'm glad that you enjoy it and have learned from it.
If you like the section on setting up an aquarium, perhaps you'd like to keep an eye on the "Fishroom" section.
A new aquatium is in progress, 72*24*24 in size, and will have some cool techie bits like, thermofilters, undergravel heating, CO2 and UV sterilization.
Still not 100% sure what's going in it yet but no doubt there will be a few catfish in there!
All the best

You are correct in that your aquarium may only contain 25G.
I have never heard of a rule that dictates the volume of water that a fish requires other than the infamous, 1 inch of fish per gallon of water nonsense.
If your question is, "how many fish can my aquarium hold?", then you may find the answer here:
