##### 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

- enter the height of the egg tank in feet
- the diameter of the tank in feet
- the weight of the liquid in pounds per US gallon

#### Results

- the volume of the egg tank in cubic feet
- the volume in cubic inches
- 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

##### Formula

V = 2/3𝝅(D/2)²H
where V is the volume
𝝅 = 3.14159265
D the diameter of the egg tank on its widest point
H the height of the egg
