How can I figure out what gallon fish tank I have?

Question

I'm guessing I need to measure the height, width, and depth, but then what do I do with those figures?

Answer 1

or you can just grab an empty milk carton (gallon size), fill it up and pour it into the tank and count however many you need...

Answer 2

Here is the information on tank sizes their gallons and the weight if filled with water. I have it on a land hermit crab site for when we find a tank and not sure of the gallon size. Small Aquariums (not recommended for beginners) Size L x W x H Filled Weight 2 1/2 gallon 12 3/16 x 6 1/8 x 8 1/8 27 lbs 5 gallon 16 3/16 x 8 3/8 x 10 1/2 62 lbs 10 gallon Leader 20 1/4 x 10 1/2 x 12 9/16 111 lbs 15 gallon High 20 1/4 x 10 1/2 x 18 3/4 170 lbs 20 gallon X-High 20 1/4 x 10 1/2 x 23 3/4 232 lbs 10 gallon Long 24 1/4 x 8 1/2 x 12 5/8 116 lbs 15 gallon Show 24 1/4 x 8 1/2 x 16 5/8 170 lbs Mid-sized Aquariums Size L x W x H Filled Weight 15 gallon 24 1/4 x 12 1/2 x 12 3/4 170 lbs 20 gallon High 24 1/4 x 12 1/2 x 16 3/4 225 lbs 25 Gallon 24 1/4 x 12 1/2 x 20 3/4 282 lbs 30 X-High 24 1/4 x 12 1/2 x 24 3/4 340 lbs 20 gallon Long 30 1/4 x 12 1/2 x 12 3/4 225 lbs 29 gallon 30 1/4 x 12 1/2 x 18 3/4 330 lbs 37 gallon 30 1/4 x 12 1/2 x 22 3/4 415 lbs 26 Flatback 36 1/4 x 12 1/2 x 16 5/8 300 lbs 23 Long 36 1/4 x 12 5/8 x 13 253 lbs 30 Gallon 36 1/4 x 12 5/8 x 16 3/4 343 lbs 38 Gallon 36 1/4 x 12 5/8 x 19 3/4 427 lbs 45 Gallon 36 1/4 x 12 5/8 x 23 3/4 515 lbs 30 gallon Breeder 36 3/16 x 18 1/4 x 12 15/16 348 lbs 40 gallon Breeder 36 3/16 x 18 1/4 x 16 15/16 458 lbs Large Aquariums Size L x W x H Filled Weight 50 gallon 36 7/8 x 19 x 19 5/8 600 lbs 65 gallon 36 7/8 x 19 x 24 5/8 775 lbs 33 gallon Long 48 1/4 x 12 3/4 x 12 7/8 382 lbs 40 gallon Long 48 1/4 x 12 3/4 x 16 7/8 455 lbs 45 gallon Long 48 1/4 x 12 3/4 x 19 510 lbs 55 Gallon 48 1/4 x 12 3/4 x 21 625 lbs 60 Gallon 48 3/8 x 12 7/8 x 23 7/8 710 lbs 80 X-High 48 7/8 x 14 x 30 3/4 990 lbs 75 gallon 48 1/2 x 18 1/2 x 21 3/8 850 lbs 90 gallon 48 1/2 x 18 1/2 x 25 3/8 1050 lbs 110 X-High 48 7/8 x 19 x 30 3/4 1320 lbs 120 Gallon 48 1/2 x 24 1/4 x 25 1/2 1400 lbs 100 Gallon 72 1/2 x 18 1/2 x 19 3/8 1150 lbs 125 gallon 72 1/2 x 18 1/2 x 23 3/8 1400 lbs 150 gallon 72 1/2 x 18 1/2 x 28 1/2 1800 lbs 180 Gallon 72 1/2 x 24 1/2 x 25 5/8 2100 lbs Hexagon tanks L x W x H Filled Weight 10 Hexagon 14 1/2 x 12 9/16 x 18 3/4 110 lbs 20 Hexagon 18 3/4 x 16 1/4 x 20 5/8 220 lbs 35 Hexagon 23 1/4 x 20 3/16 x 24 3/4 390 lbs 60 Hexagon 27 1/4 x 24 1/8 x 29 1/2 750 lbs Metric conversions of tank length, to nearest centimeter: inches centimeters 8 1/4 21 12 3/16 31 13 5/8 35 16 3/16 41 20 1/4 51 24 1/4 62 30 1/4 77 36 7/8 94 48 ¼ 123 48 7/8 124 72 1/2 184

Answer 3

That will tell you the volume of the tank in linear measurements but you must look in the dictionary or a math textbook to find oout what a gallon of water measures then convert the numbers. The easiest is to get a gallon jug and count how many it takes to fill it.

Answer 4

Try filling your fishtank to the brim and then drain the fish tank, seriously, take your measurements of the tank and phone the petshop and ask them how many gallon tank that is, or you can do multiplications as the previous answer suggests

Answer 5

If your tank has the following measurements it is a 10 gallon tank: 20x10x11.

Answer 6

Measure lengthxwidthxheight=m3
Then go to any conversion site and type in the figure here is any old link I checked and it worked fine.
