Spike's Calculators

Calculate the volume and capacity of a bowl tank.

The bowl tank here is semi-sphere, where the height is equal to half the diameter. This calculator uses inches for measurements.

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

- enter the diameter of the bowl tank in inches
- the weight of the liquid in pounds per US gallon

- the volume of the bowl 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 =2/3𝝅(D/2)³ where V is the volume of the tank 𝝅 = 3.14159265 D the tanks' diameter

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)
