# Bowl Tank

Calculate the volume and capacity of a bowl tank.
The bowl tank here is semi-sphere, where the height is equal to half the diameter. 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 diameter of the bowl tank in inches
2. the weight of the liquid in pounds per US gallon

#### Results

1. the volume of the bowl tank in cubic inches
2. the volume in cubic feet
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 =2/3𝝅(D/2)³
where V is the volume of the tank
𝝅 = 3.14159265
D the tanks' diameter
```
##### Conversions
```one cubic inch (in³) = 0.000578703703703704 cubic feet (ft³)
one cubic inch (in³) = 0.000016387064 cubic metres (m³)
one cubic inch (in³) = 0.00432900432900432 gallons (gal) US
one cubic inch (in³) = 0.00360465014990905 gallons (gal) Imperial
one cubic inch (in³) = 0.016387064 litres (L)
