You can convert a tanks storage capacity between numerous quantities including – Litres, m3, Gallons (UK), Gallons (US), Barrels and ft3. Not only that, but if you already have an existing measurement unit you wish to convert, our tank volume converter will allow you to do this quickly and easily. Olympic-size swimming pool contains 2,500,000 L of water, assuming a nominal depth of 2 m. The length of the pool is 50 m, width 25 m, and the depth varies: 2.0 m is the minimum, but 3.0 m is the recommended depth. The results of your inputs will be displayed in a range of measurement units including – Litres, m 3, Gallons (UK), Gallons (US), Barrels and ft 3. To calculate the Olympic swimming pool volume, you need to know its dimensions. Optionally with all tank types, you can also include the Liquid Height, which will then allow you to work out the spare capacity available in the tank. If you have Rectangular Tanks, you will need to include the Length, Width and Height of the tank. You will need to add the Diameter and Width for both Horizontal Cylindrical Tanks, Vertical Cylindrical Tanks. Next you need to select the measurement unit that your tank measurements are in, in order to ensure your results are accurate. A rectangle with four sides of equal length is a square. Rectangle is a quadrilateral with four right angles. Once you know your tanks dimensions, you simply need to select the type of storage tank you are calculating the volume for by selecting one of the tank type options – Horizontal Cylindrical Tanks, Vertical Cylindrical Tanks and Rectangular Tanks. Calculate the total and filled volumes in gallons and liters of tanks such as oil tanks and water tanks. A rectangular fish tank with length, width and height as 5,7 and 10 in has Aquarium Size of.
