Tank Volume Calculator

Pick a tank shape, enter its dimensions and, if you want, the depth of liquid inside. Tank Volume Calculator returns the total capacity and, when you enter a filled depth, the volume and percent full, in US gallons, imperial gallons, liters, cubic meters and cubic feet.

What you get
• Ten shapes: horizontal and vertical cylinders, rectangle, ovals, capsules, elliptical tanks and dish-ended tanks
• Dimensions in meters, miles, yards, feet, inches, kilometers, centimeters, millimeters, micrometers, nanometers or angstroms
• Optional filled depth for the liquid volume and percent full
• Results in US gallons, imperial gallons, liters, cubic meters and cubic feet

Where it helps
• Sizing a fuel, water or propane tank before buying
• Estimating how much liquid a tank holds at a given level
• Checking the capacity of a rain barrel or storage tank
• Working out how full a tank is from the depth on a dipstick

The filled depth cannot be larger than the tank's diameter or height.

• Light and dark theme
• 28 languages, with right-to-left layout where it belongs
