Spike's Calculators

Calculate the volume, capacity, and surface area of a spherical dome tank. The spherical dome tank is a sphere cap and requires a height measurement and the base length of the tank. 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 height of the spherical dome tank
- the tank's base length
- the weight of the liquid in pounds per US gallon

- the volume of the spherical dome 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

R= ((C/2)²/H+H)/2 V= H²Π/3(3R-H) where R is the radius of the sphere V the volume of the tank C the base length of the cap H the height 𝝅 = 3.14159265
