Water & Volume Calculators

These calculators answer 'how many gallons' for a pipe, a tank or a pond. The Pipe Volume Calculator gives the liquid a full length of pipe holds from its inside diameter — the bore, not the nominal size, because volume changes with the square of the diameter. The Tank Volume Calculator handles vertical and horizontal cylinders, rectangular tanks and horizontal ovals, and gives the volume at a partial fill depth, which for a horizontal cylinder follows a curve rather than a straight line. The Pond Calculator estimates a garden pond's water volume and the flat liner sheet it needs, applying a basin factor for the volume lost to sloping sides and shelves. For the weight of a pipe rather than its contents, use the Pipe Weight Calculator in the Materials category.
