Hemisphere Dome Tank

Calculate the volume of a dome-shaped tank that is a hemisphere (half sphere).

Half of the length's base equals the height in this type of tank. This calculator uses inches for measurements.

Approximate weight of Fuel or Water

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

Calculator

1. enter the tank's base length
2. the weight of the liquid in pounds per US gallon

Results

1. the volume of the tank in cubic inches
2. volume in cubic feet
3. volume in cubic metres
4. tank capacity in US gallons
5. capacity in Imperial gallons
6. capacity in litres
7. weight of the liquid when the tank is full
8. the surface area of the tank in square inches
9. the surface area in square feet
10. the surface area in square millimetres
11. the surface area in square metres

Formula

V = 2/3Πr³
where V is the volume
Π = 3.14159265
r half the length of the tank base
