Cone Tank - Feet

Calculate the volume, capacity, and surface area of a cone-shaped tank. This calculator uses feet 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. the height in inches
2. the cone's base diameter in feet
3. the weight of the liquid in pounds per US gallon

Results

1. the volume of the cone tank in cubic feet
2. he volume in cubic inches
3. the volume in cubic metres
4. the tank capacity in US gallons
5. the capacity in Imperial gallons
6. the capacity in litres
7. full tank liquid weight based on lbs/gal US
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 = 1/3𝝅(B/2)²H
where V is the volume of the cone
𝝅 = 3.14159265
B the  diameter at the base of the cone 
H the height of the cone
