Spike's Calculators

Calculate a horizontal cylinder-shaped tank's volume, capacity, and surface area.

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

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

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

- the volume of the tank in cubic inches
- volume in cubic feet
- volume in cubic metres
- tank capacity in US gallons
- capacity in Imperial gallons
- 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=𝝅(D/2)*L where V is the volume 𝝅 = 3.14159265 D the diameter L the length of the tank
