The final equation is rMajor x rMinor x h x π = Volume.įinding these measurements is often more challenging. Once you have those, measure the height, and multiply everything by Pi. You have to find the radius of the long side and short side. Calculating Volume for Elliptical AquariumĪn elliptical Aquarium can sometimes be a little more challenging to figure out. If it’s not, you don’t have a half-cylinder. That length should be equal to the radius. Measure from the end of that radius to the edge. Then measure the radius on the back of the tank. If you’re not sure the tank is a half-cylinder, find the radius. When you measure the diameter for a half-cylinder, use the back length. If you have a half-cylindrical tank, you can use the same equation for cylindrical. Both of these values will give you very close results. If you don’t have a calculator, Pi can equal 3.16 or 22/7. Square the radius, and multiply it with the height and Pi. Then divide it in half to get the radius. To get the volume, you have to measure the diameter of the circle. If there is a difference, it may be an ellipse or an oval. There shouldn’t be a change anywhere on the circle. To check, the measurement of the diameter should be the same. Make sure your tank is actually a cylinder though, if it is not, you may need another formula. Circles have their own math for aquariums.
If you have a cylindrical tank, there is a unique formula you need. Calculating Volume for Cylindrical Aquariums Just make sure they are the same for each measurement.

The whole equation is: (w x l) + π(((w-full w) x l)/2)x h = full volume. You will get the value in the cubic form of the measurement you used. Now add the two areas together and multiple by the height. Multiply the calculated width, length and divide them in half. With the elliptical, you take the width from the furthest portion of the oval. For the width, you only measure the distance to where the elliptical part starts. Then you have to find the elliptical area.įor the rectangle, you multiply width, and length.
Calculating Volume for Rounded Aquariumsįiguring out the volume of a rounded or bow-front aquarium can be a little more complicated.įirst, you’re going to calculate the rectangle area portion. Once you have the total volume of the aquariums, you can find the gallons. Multiple the individual pieces and add them up. All you have to do is take the measurements of each. If your aquarium is a strange shape, you can sometimes break it into multiple rectangles. If you’re not sure you have a cube, measure all three dimensions. You only need to measure one and then cube it. The height, width, and length are all the same in a cube. You can use any unit, but keep them all the same for each measurement. So if you measure it in inches, it will be cubed inches. This calculation will give you cubed versions of whatever unit you used. All you have to do is multiply the height, width, and length of the tank. They are also some of the most straightforward tanks to calculate volume. They are usually the largest tanks, and you see them everywhere. Rectangular or square aquariums are the most common type of tank.
