Spike's Calculators

Calculate the volume, capacity, and surface area of a truncated cone tank. A truncated cone tank is a cone where the top part is cut off parallel to its base.

one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds

Note: measurement used in the calculation is the diameter length, not the radius length!

- the top diameter in inches
- base diameter in inches
- truncated cones' height in inches
- the weight of the liquid in pounds per US gallon

- the volume of the truncated cone tank in cubic inches
- the volume in cubic feet
- the volume in cubic metres
- the tank capacity in US gallons
- the capacity in Imperial gallons
- the capacity in litres
- full tank liquid weight based on lbs/gal US
- the surface area of the tank in square inches
- the surface area in square feet
- the surface area in square millimetres
- the surface area in square metres

V = 1/3𝝅((T/2)²+(T/2)(B/2)+(B/2)²)H; where V is the volume of the truncated cone 𝝅 = 3.14159265 T the upper diameter B the lower diameter H the height of the truncated cone

one cubic inch (in³) = 0.000578703703703704 cubic feet (ft³) one cubic inch (in³) = 0.000016387064 cubic metres (m³) one cubic inch (in³) = 0.00432900432900432 gallons (gal) US one cubic inch (in³) = 0.00360465014990905 gallons (gal) Imperial one cubic inch (in³) = 0.016387064 litres (L)
