If the tank's height, level and diameter are measured in inches, then the output will be in cubic inches and gallons.
If the tank is measured in feet, then the output will be in cubic feet and gallons.
If measured in meters, the results will be in cubic meters and liters.
Inputting tank height = 12, liquid level = 3 and tank diameter = 6, then clicking "Inches" will display the total tank volume in cubic inches and US Gallons and will also show the volume at the 3 inch level.
If the tank is filled with water, this calculator also displays the weight of water at the liquid level and at full volume.
In addition, a dipstick chart is automatically generated. The default dipstick chart is in increments of one but you can change that by clicking on one of the increment buttons.
